Question 403614
The length of the side of a rectangular desk is given by 6x - 3y cm. The length of the front is given by 6x + 3y cm. What is an algebraic expression for the area of the top of the rectangular desk? Include correct units as part of your answer. 


The length of the side of a rectangular desk is given by 6x - 3y cm. 
The length of the front is given by 6x + 3y cm. 

...
Area = L*W
Area = (6x-3y)(6x+3y)
Area = (36x^2-9y^2) cm^2
