The length of a rectangle is five times its width.
If the area of the rectangle is 180m^2, find its perimeter.

Question

The length of a rectangle is five times its width. 
If the area of the rectangle is 180m^2, find its perimeter.

anonymous · Answer

You are given with;

L = 5W

So:

Area is given by:

$$Area = L \times W$$

$$180 = L \times W$$
$$180 = 5 W^2 \implies W^2 = 36$$

Find W here..

Then to find perimeter use:

$$Perimeter = 2(L + W)$$

anonymous · Answer

x(5x)=180
5x2=180
x=36
2x+2(5x)=72+360=432

ANSWER = 36

anonymous · Answer

answer is not 36.

anonymous · Answer

a*5a =180m^2
a= square (36) m
a = 6
perimeter = 5*6 +5 = 36 meters,
 my guess

anonymous · Answer

Multiplied by 2 instead..

anonymous · Answer

hmmm okay ..... ill redo and see if i made a mistake

anonymous · Answer

yeah
you are right
72 is the answer since it's 2 (with + length)

anonymous · Answer

W = 6 here..

So L = 30 here..

Just add them and then Multiply by 2, to get Perimeter..
