Question

The length of a rectangle is eight more than twice its width. The perminiter is 96 feet . find the deminsions. With the variable, equation, and solution.

Answer 1

Explanation:

L=8+2W

P=2L+2W

P=2(8+2W)+2W

P=16+4W+2W

P=16+6W

P=96

96=16-6W

80=6W

W=13.3333

Answer 2

Explanation:

lenght = x + 8

width = x

`perimeter = 2(x + 8) + 2(x) \\ 96= 2x + 16 + 2x \\ 4x = 96 - 16 \\ x = (80)/(4) \\ x = 20`

then

Lenght = x + 8 = 20 + 8 = 28

Width = x = 20
