Question

A = 2(lw + wh + lh), for l given, w = 5, h = 3, and A = 158

Answer 1

ok so plug in your given values
A = 2(lw + wh + lh)
158=2(l(5)+5(3)+l(3))
simplify
158=2(5l+15+3l)
get rid of the parenthesis by multiplying everything in them by 2
158=10l+30+6l
combine like terms
158=16l+30
128=16l
divide both sides by 16
l=8
