The length and width of a rectangle are consecutive integers. The perimeter of the rectangle is 86 inches. Find the length and width of the rectangle.

Answer 1

L and W are consecutive integers

P = 86 = 2L +2W

L+W = 43

43/2 = 21.5

round up and down to get 21 and 22

try 21 and 22

86 = 2(21) + 2(22) = 42+44
