To solve, let's compute the area of each doghouse. Apply the
formula of area of rectangle which is:


So, the area of the smaller doghouse is:

`A_S=2 xx1`


And the area of the larger doghouse is:



Then, get the difference of the areas.

`A_L - A_s= 8-2 = 6`

Hence, the larger doghouse is 6 square feet greater than the smaller doghouse.
