Get the area of the dog houses.

Since it is stated that the dog houses will be rectangular, you use the formula:


` `

or simply multiply the dimensions.

`A_s` = area of the smaller house 

`A_s = 2*1 = 2 sq. ft`

`A_l` = area of the larger house  

`A_l = 4*2 = 8 sq. ft`

To solve how many greater is the larger house, subtract the area of the smaller from the area of the larger houes.

`A_l - A_s = 8 - 2 = 6`

Therefore, the larger house is greater by 6 sq. ft.
