The formula for finding the perimeter, P, of a rectangle with length, l, and width, w, is given:
P = 2l + 2w Which formula shows how the length of a rectangle can be determined from the perimeter and the width? p P A.) l = ------- - 2w C.) l = ----- + w 2 2 P - 2w P - 2 B.) l = --------- D.) l = --------- 2 2w
Solve the given equation for the length, l.
P = 2l + 2w P - 2w = 2l {subtracted 2w from each side} P - 2w B.) l = ---------- {divided each side by 2} 2 Ask Algebra House Comments are closed.
