Question

The perimeter of a basketball court is 90 meters and the length is 6 meters longer than twice the width. What are the length and the width?

Answer 1

Use the length-width relation to restate the perimeter in terms of length and width.

Answer 2

if length = 6 meters longer than twice the width, then
L = 2W + 6
P = 2W + 2L
90 = 2W + 2(2W + 6)
90 = 6W + 12
78 = 6W
W = 13
L=2(13)+6
L=32

W=13, L=32

Answer 3

got it thanks
