# How do you solve A = L * W * H for L?

Dec 4, 2016

$L = \frac{A}{W \cdot H}$

#### Explanation:

Divide each side by $W \cdot H$ to isolate $L$ and keep the equation balanced:

$\frac{A}{W \cdot H} = \frac{L \cdot W \cdot H}{W \cdot H}$

$\frac{A}{W \cdot H} = \frac{L \cdot \cancel{W} \cdot \cancel{H}}{\cancel{W} \cdot \cancel{H}}$

$L = \frac{A}{W \cdot H}$
