Question

solve the literal equation for the indicated variable. perimeter of a rectangle: ( p = 2l + 2w ); solve for ( l ). ( l = )

Explanation:

Step1: Subtract \(2w\) from both sides

$$P - 2w=2l + 2w-2w$$
$$P - 2w = 2l$$

Step2: Divide both sides by \(2\)

$$\frac{P - 2w}{2}=\frac{2l}{2}$$
$$l=\frac{P - 2w}{2}$$

Answer:

\(l=\frac{P - 2w}{2}\)
