Question

the length of a rectangle is 1 inch more than twice its width. if the perimeter of the rectangle is 74 inches, find the dimensions of the rectangle.

Answer 1

L = 2W + 1..................(1)
2L + 2W = 74
2L = -2W + 74..............(2)   Adding  (1) and (2):-

3L = 75
L = 75/3 = 25

W = (25 - 1) / 2 = 12

length is 25 inches and width = 12 inches
