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

QUESTION POSTED AT 05/12/2019 - 02:17 PM

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.

For this question the answer is 2.5m (B)

You find this by: L=0.85m

W=0.4m

A rectangle had 4 sides (2 lengths and 2 widths)

So...

To find 1 length and 1 Width you do 0.85+0.4=1.25m

Now you want to find the other 2 sides (L and W)

You can do: the same method and add it to 1.25m OR...

You can do (I prefer this one): (0.85+0.4)x2=?

This is the same as 0.85+0.4=1.25

1.25x2=2.5m

You find this by: L=0.85m

W=0.4m

A rectangle had 4 sides (2 lengths and 2 widths)

So...

To find 1 length and 1 Width you do 0.85+0.4=1.25m

Now you want to find the other 2 sides (L and W)

You can do: the same method and add it to 1.25m OR...

You can do (I prefer this one): (0.85+0.4)x2=?

This is the same as 0.85+0.4=1.25

1.25x2=2.5m

The surface area of a rectangular prism is this:

SA = LW + LH + LH

Here are the changes:

L --> (2/3)L

W --> 4W

H --> H/2

So, the new surface area is:

SA' = (2/3)L (4W) + (2/3)L (H/2) + 4W (H/2)

SA' = (8/3) LW + (1/3) LH + 2 WH

SA = LW + LH + LH

Here are the changes:

L --> (2/3)L

W --> 4W

H --> H/2

So, the new surface area is:

SA' = (2/3)L (4W) + (2/3)L (H/2) + 4W (H/2)

SA' = (8/3) LW + (1/3) LH + 2 WH

The basic definition of a perimeter is the boundary line of an object. For shapes and figures, this is basically the sum of the outermost sides that define the object. Since an octagon has eight sides, with each side measuring 12m, the perimeter can be obtained by multiplying 12 m by 8 sides, or in equation form:

P = 8(12)

Among the choices, this is letter B.

P = 8(12)

Among the choices, this is letter B.

**Answer:**

**Option (c) 7.6 cm is the correct answer**

**Step-by-step explanation:**

Three sides of a quadrilateral measure 2.5 cm, 1.8 cm, and 9 cm.

Perimeter of the quadrilateral is 29.9 cm

Then we have to find the length of 4th side.

Since perimeter of any quadrilateral = sum of all four sides

so by using this formula

20.9 = 13.3 + x

x = 20.9 - 13.3

x = 7.6 cm

**Option (c) 7.6 cm is the correct answer**
