1)
The area is simply the base multiplied by the height:
%282x%2B1%29%282x%2B1%29=2x%2A2x%2B2x%2B2x%2B1=4x%5E2%2B4x%2B1 foil the terms
So the area is 4x%5E2%2B4x%2B1


2)Again to find the area, we just multiply the base and the height:
%283x%2B2%29%283x-2%29=3x%2A3x%2B6x-6x-4=9x%5E2-4 foil the terms
So the area is 9x%5E2-4
