Anthony drew a pentagon with each side measuring 6 inches. Carol drew hexagon with each side measuring 5 inches. Which shape has a greater perimeter? Write an equation to help explain your answer.

Answer:

The perimeter of both shapes is equal.

Step-by-step explanation:

We have been Anthony drew a pentagon with each side measuring 6 inches.

We know that perimeter of a regular polygon is n times the side length of polygon, where n represents number of sides in a polygon.

We know that a pentagon has 5 sides, so perimeter of pentagon would be 5\times 6\text{ inches}=30\text{ inches}.

Carol drew hexagon with each side measuring 5 inches. We know that a hexagon has 6 sides, so perimeter of hexagon would be 6\times 5\text{ inches}=30\text{ inches}.

Therefore, the perimeter of both shapes is equal.

Find the value of L. Perimeter = 20. Width is 6. So what is L? On a square


Well first of all, that's not a square.  On a square, all 4 sides are
the same, and the length is the same distance as the width.  If the
width of a square is 6, and all four sides are the same, then the
perimeter is (4 x 6) = 24. 

So the shape in your question may be a rectangle, but it's definitely
not a square one.

The perimeter is the distance an ant has to walk if you put him down
on one corner and he walks all the way around the shape until he gets
back to where he started from. 
That's the perimeter.

If you set the ant down on the corner of a rectangle, then he walks the
length, then the width, the the length again, then the width again, and
he's back where he started.

That was 2 lengths and 2 widths ... the perimeter of every rectangle.

Take 2 widths away from the perimeter, and you have 2 lengths left.  OK ?

You said that the width of your rectangle is 6.  Two widths is 12.
Take the 2 widths away from the perimeter, and you're left with (20 - 12) = 8.
But that's 2 lengths !
So the length is half of 8  =  4 .

QUESTION POSTED AT 05/12/2019 - 02:44 PM

The perimeter of a rectangle is 13cm and its width is 11/4. find its length.

Perimeter = 2 length + 2 width

P = 2(l) + 2(11/4)

13 = 2l +2* \frac{11}{4}

13 = 2l + \frac{2}{1} * \frac{11}{4}

13 = 2l + \frac{22}{4}     (subtract 22/4 from each side)

13 -\frac{22}{4} = 2l

13 -\frac{11}{2} = 2l

\frac{26}{2}  -\frac{11}{2} = 2l

\frac{15}{2}} = 2l

7.5 = 2l    (divide each side by 2)

7.5 ÷ 2 = l

3.75 = l

The answer is 3.75 or 3 \frac{3}{4}

A bedroom has perimeter of 46 feet. if the length of the the bedroom is 11 feet, what is the wigthof the bedroom.


Perimeter is basically the combines sum of all the bedroom's sides. It is a rectangle, therefore the formula is 2L+2W=P.

Since you are given the overall perimeter, you just plug-in the info you already have into the question. Like this: 2(11)+2(W)=46

Then solve the equation.

(2*11)+2W=46

22+2W=46

2W= 24

W=12 Feet. The width is 12 feet.

Which equation could be used to find the perimeter of a rectangle that has a width of 12 cm and a length of 16 cm? a. P = 2 · 12 + 2 · 16 b. P = 2 · 12 + 16 c. P = 12 · 16 d. P = 12 + 16

It would be a. because a rectangle has 2 pairs of congruent sides so since the width is 12 and there are 2 sides with that measurement it would be 2(12) and the same goes for the length, and then you add them together.

QUESTION POSTED AT 05/12/2019 - 09:00 AM

The length of a rectangle is 9 inches more than three times the width. the perimeter is 98 inches. find the length and width

Here is the equation:

Your goal is to get a number variable

2w+2(3w+9)=98

Solve the parentheses first, namely "w" by itself on one side

2w+6w+18=98

Add common  values

8w+18=98

Minus 18 from both sides

8w+18-18=98-18

It is now

8w=80

Now, divide 80 by 8

80÷8=10

w=10

Lets check:

2(10)+ 2(30+9)=98

20+60+18=98

Which is correct

So that means each side of the width is 10 inches
and each length side is 39 inches

Answer: So that means that width side is 10 inches each and each length side is 39 inches each. 10+10+39+39=98 inches

Find the width of a rectangle with a perimeter of 90 and a length of 15

Answer:

width = 30 units .

Step-by-step explanation:

Given : perimeter of 90 and a length of 15.

To find : Find the width of a rectangle.

Solution : We have given  

Perimeter = 90

Length = 15.

Perimeter of rectangle = 2 ( length+ width).

Plugging the values

90 = 2 (15+ width).

On dividing both sides by 2

45 = 15 + width

On subtracting both sides by 15

45 - 15 = width.

30 units = width.

Therefore, width = 30 units .
