Question

the width of a rectangle is 5 inches less than its length. its area is 50square inches. find the deminsions of the rectangle

Answer 1

area of a rectangle A = W * h
in this case: W = h-5
A = (h-5) * h = 50 -> h^2 - 5h = 50
h^2 - 5h - 50 = 0
h= 10
W = 10-5 = 5
height: 10 inches width: 5 inches

Answer 2
