Question

The formula for the perimeter of a rectangle is P = 2l + 2w, where P is the perimeter, l is the length, and w is the width. Solve for w.

Answer 1

Explanation:

Answer 2

(P-2l)/2 =w

Explanation:

P = 2l + 2w

Subtract 2l from each side

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

P-2l = 2w

Divide by 2

(P-2l) /2 = 2w/2

(P-2l)/2 =w
