Question

the formual p=2(l+w) can be used to find the perimeter if a rectangle with a length,l and a width, w.the perimeter of a rectangular shipping crate with a length of 9 feet is 30 feet. what is the width, in feet, of the crate

Answer 1

p = 2(l + w)
p = 30
l = 9

30 = 2(9 + w)
30 = 18 + 2w
30 - 18 = 2w
12 = 2w
12/2 = w
6 = w...so the width is 6 ft
