Question

S=4LW+2WH S=136 L=7 W=4. what is h?

Answer 1

h = 3

Explanation:

First, substitute for each known variable

136=4(7)(4)+2(4)H

136=8h+112

Then flip the equation

8h+112=136

Subtract 112 from both sides

8h = 24

Then divide 8 from both sides

h=3

Answer 2

H = 3

Explanation:

`S=4LW+2WH\\\\\text{We have}\ S=136,\ L=7,\ W=4.\ \text{Substitute:}\\\\136=4(7)(4)+2(4)H\\\\136=112+8H\qquad\text{subtract 112 from both sides}\\\\24=8H\qquad\text{divide both sides by 8}\\\\3=H\to H=3`
