What Is The Length And Width Of A Rectangle With A Perimeter Of 162 In And A Length Of Eight Times The Width?
Answer:
Lets suppose :
Width=X
Length=8X
We are given that:
Perimeter= 162
The formula for the perimeter of a rectangle is:
Perimeter=2(L+W)
Where:
L=length
and
W=width
So plugging in the values in the formula:
Perimeter=2(L+W)
162=2(8X+X)
Adding:
162=2(9x)
Dividing:
162/2=9x
So:
81=9x
Dividing:
x=81/9
So:
x=9
Hence the utility of the width is 9
To find the length:
Length=8x
=8(9)
=72
Hence the width is 72
