the perimeter of a rectangle is 10(2x 1) inches. if the lengths of the sides are x 7 and 2x 11 and 3x 8 and x 10 inches, what is the length of each side of the rectangle

x + 7 + 2x + 11 + 3x + 8 + x + 10 = 10(2x + 1)
7x + 36 = 20x + 10
20x - 7x = 36 - 10
13x = 26
x = 26/13 = 2

Therefore, the lengths are 2 + 7 = 9; 2(2) + 11 = 4 + 11 = 15; 3(2) + 8 = 6 + 8 = 14; 2 + 10 = 12

{this is not a rectangle though}
