Final answer:
To isolate L in the equation A = L • W • H, divide both sides by W and H, resulting in the solution L = A / WH.
Step-by-step explanation:
To solve for L when given the equation A = L • W • H, where A is the area, W is the width, and H is the height, we rearrange the equation to solve for L.
The correct expression that isolates L is:
L = A / (W • H)
So out of the options given, the correct one would be C) L = A / WH. You divide both sides of the original equation by W and H to isolate L on one side, resulting in L being by itself.
