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 width.

Answer 1

Let w = width of the court
Then, l = 2w + 6
2w + 2(2w + 6) = 90
2w + 4w + 12 = 90
6w + 12 = 90
6w = 78
w = 13
l = 2*13 + 6 = 32
Length = 32 and Width = 13

Answer 2

Now form an equation to represent the perimeter... and then solve for x
