Paul is building a new dog house for his dogs. The old dog house has a base that measures 2 ft by 3 ft. The plans for the new dog house have a base that measures 3ft x 5 ft. How much larger is the area of the new dog house than the old dog house?
A. 12 ft²
B. 9 ft²
C. 6 ft²
D. 3ft²
B. 9 ft²
Explanation: To find the answer you must find the difference of the two areas. You must first
find the area of old dog house. So, 2ft x 3ft = 6ft² You then need to find the area of the new
dog house base. So, 3ft x 5ft = 15ft². You then need to find the difference, so 15 - 6 = 9.
