A rectangular rug has a perimeter of 460 meters. The width of the rug is five meters more than 4 times the length

Answer 1

W = 5 + 4L

P = 2(L + W) = 460

Substitute Eq 1 into the perimeter equation, you get

2(L + 5 + 4L) = 460

2(5L + 5) = 460

10L + 10 = 460

10L = 450

L = 450 / 10 = 45 m

W = 5 + 4L

= 5 + 4(45)

= 5 + 180 = 185 m
