Question

Write the sentence as an equation. Choose a variable to use. The width of a rectangle is half the length, and the perimeter is 32.

Answer 1

W = 1/2 L
2W + 2L = 32
Then Solve for one variable

Answer 2

l=length
w=width

2l + 2w = perimeter = 32

2w=l (because the width is half the length)

Therefore:

2l+l=32
3l=32
l=32/3= 10.67 (2d.p.)

So, l=10.67, and w=10.67/2=5.33

Answer 3

The width of a rectangle is half the length, and the perimeter is 32.
