C because 23.6 times two is 47.4 and 52.9 times two is 105.8, add those two together to get c

Area of a rectangle is the length x width.

If you had a rectangle with the side measurements of 2in. and 4in. your area would be 8in. squared

QUESTION POSTED AT 20/02/2020 - 10:53 PM

**Answer:**

**The possible answer is 10 in. **

**Step-by-step explanation:**

Two sides of a triangle measure 5 in. and 12 in.

If three side of triangle are a, b and c then sum of two side is always greater than third side.

**Sum of two side greater than third side. **

a+b>c

a+c>b

b+c>a

**Difference of two side is less than third side.**

a-b<c

b-c<a

a-c<b

Here, we are given two sides of a triangle 5 in and 12 in.

Possible length of third side be

**12-5 < c < 12+5 **

**7<c<17**

Third side must be lie between 7 to 17.

According to option, Third side must be equal to 10 in.

**Hence, The possible answer is 10 in. **

Let the side of one square be x.

The maximum perimeter will be when the squares will be lined end to end.

This will be:

x + 9x + 9x + x

= 20x

The perimeter of the figures formed will be less than or equal to 20x.

**Answer:**

**Area of square is 25 inches² **

**Step-by-step explanation:**

Given : A square photograph has a perimeter of 20 inches.

We have to find the area of the photograph.

**We know perimeter of square is 4a , where a is side of square**

Given : perimeter of square = 20 inches

4a = 20

Divide both side by 4, we get,

**a = 5 inches**

**Also, Area of square = side × side **

Area of square = 5 × 5

Area of square = 25 inches²

**Thus, area of square is 25 inches² **

**Answer:**

**Step-by-step explanation:**

He can not construct a triangle because when you add up two of the side lengths they are supposed to be greater the the remaining side length for example 8+14>23 would be incorrect because 8+14 equals 22 which means it would not be greater than 23 and therefore that is why he can not construct a triangle.

QUESTION POSTED AT 20/02/2020 - 10:16 PM

**Answer:**

b2 = 14

b1 = 7

**Step-by-step explanation:**

Area_triangle = 1/2 * b * h

Area _trapezoid = (b1 + b2)*h1/2

Since the areas of the two figures are the same, we get

1/2 * b * h = (b1 + b2)*h1/2 multiply both sides by 2.

b*h = (b1 + b2) * h1

b=21

h = 6

2*b1 = b2

21*6 = (b1 + 2*b1)*6 Divide by 6

21 = 3*b1 Divide by 3

7 = b1

2*b1 = b2

b2 = 14

The perimeter of a polygon is proportional to its side so:

18 : 16

24 : p

p = 21.3 meters

Area is proportional to the square of the side of a polygon so:

18² : 1000

24² : x

x = 1,777.8 square meters

Note: The value of the perimeter should not be less than the length of one side. The data may be incorrect. Regardless, the method will be the same.

First draw a picture (see attached).

You want to find the diagonal of the cube, length AB.

The right triangle formed is trianagle ABD.

AD = 10m

DB will be the hypotenuse of triangle BCD.

.

If we know the length of AD and DB, we can find AB.

**In fact, the diagonal of any cube is √3 times the side length of the cube.**

Let *s* be the side length (as in AD or CD in the attached) and

h be the hypotenuse of the base, (DB in the attached) and

*d* be the diagonal of the cube (AB in the attached).

The hypotenuse of the base will be:.

So we are trying to find this red line's length.

We can either find it directly, or use the blue line firs, and then use it as a leg for the green triangle.

So the blue leg is a hypotenuse for two of the edges. So:

from the Pythagorean Theorem

OR

Which works out to:

So now that we have that, using the Pythagorean Theorem again gives:

So the length of the red line is found that way.

But wait! There's more!

As it turns out, the red line can be found with an easier way that works with cubes and boxes (cuboids). It's really easy:

Where a, b, and c are all 10m, and d is the red line. This greatly reduces the math:

which gives the same answer as above, which you can see.
