You can put this solution on YOUR website! The area is (9x - 2y)(9x + 2y) = 81x^2 - 4y^2 cm^2 (by the difference of two squares theorem).
You can put this solution on YOUR website! side of a rectangular desk is given by 9x - 2y cm.
The length of the front is given by 9x + 2y cm.
...
Area = L*W
(9x-2y)(9x+2y)=Area
(81x^2-4y^2)cm^2= Area
