Does anyone know the answer to this question?

Define x :

Width = x
Length = x + 8


Solve x :

Given that the perimeter is 90:
*listing from the top lefthand corner, clockwise
(x) + (x + 8) + (x) + (8) + (x+8) + (x) + (x+8) + (x) + (8) + (x+8) = 90
8x + 48 = 90
8x = 42
x = 5.25


Find Length and Width :

Width = x = 5.25 cm
Length = 5.25 + 8 = 13.25 cm


Find Area :

4 rectangles = 5.25 x 13.25  x 4 = 278.25 cm²


Area = 278.25 cm²

Because the price would be 25% off the 25% off, which for example would be 25% off 20 dollars, which it would be 15 dollars. then, 20% off 15 dollars would be 11.25, and not 10.
