Question

Solve the formula for the specified variable.
S = ( 2 W + 2 H ) L + 2 W H
L = ???

Answer 1

Answer:
`\bold{L=(S-2WH)/(2W+2H)}`

Explanation:

`S=(2W+2H)L+2WH\\\\\\\underline{\text{Subtract 2WH from both sides:}}\\S-2WH=(2W+2H)L\\\\\\\underline{\text{Divide both sides by (2W + 2H):}}\\\\(S-2WH)/(2W+2H)=L`
