Dustin Kirk · Answer 1

L = 6W

Area A = LW = 600. So, 6W (W) = 600, W2 = 600/6 = 100, so W = 10. Then L = 600/10 = 60.

Perimeter P = 2L + 2W = 2 (60) + 2 (10) = 120 + 20 = 140.

Elian Brennan · Answer 2

A) l * w = 600

B) l = w * 6

Solving A) for length

A) l = 600 / w

B) l = w * 6

600 / w = w * 6

6w^2 = 600

6w^2 - 600 = 0

width = 10

length = 60
