Question

A rectangle with a perimeter of 102 inches is half as wide as it is long. Write and solve an equation to determine the length of this rectangle in inches.

Answer 1

One side is 17 inches and the tother is 34

So you could use

2(x) + 2(y) = 102

x=7 y=32

I hope that helps any!

Answer 2

let width be x inches so the length will be 2x inches.
so we have
2*2x + 2x = 102
6x = 102
x= 17


so the length = 2x = 2*17 = 34 inches
