Paxton Mcfarland · Answer 1

A) 2L + 2W = 48

B) L * W = 140

B) W = 140 / L

Inputting this to equation A)

A) 2L + 2 * (140 / L) = 48

L + 140/L = 24

Multiplying both sides by "L"

L² + 140 = 24L

L² - 24L + 140 = 0

(L - 10) * (L-14) = 0

L = 10

L = 14

If length = 10 then width = 14

If length = 14 then width = 10
