The length of a rectangle is 5 more than the width . If perimeter is 26, what is the area
L = W + 5
Perimeter = 2 (L + W)
26 = 2 ( W + 5 + W)
26 = 2 ( 2W + 5) divide both sides by 2
13 = 2W + 5 subtract 5 from both sides
8 = 2W divide both sides by 2
4 = W
And L = W + 5 = 9
And
Area = W * L = 4 * 9 = 36 units^2
Area A = (26/4+2.5)(26/4-2.5)
