Question

1. match the size of the addition and cost per square foot with the total cost to build the addition.
2. an addition that is 20 ft. by 14 ft. and cost $95 per square foot
3. an addition that is 12 ft. by 17 ft. and cost $105 per square foot
4. an addition that is 13 ft. by 18 ft. and cost $98 per square foot

a. $21,420
b. $26,600
c. $22,932

Explanation:

Step1: Calculate area of first addition

Area = 20×14 = 280 square - feet. Total cost = 280×95 = $26600.

Step2: Calculate area of second addition

Area = 12×17 = 204 square - feet. Total cost = 204×105 = $21420.

Step3: Calculate area of third addition

Area = 13×18 = 234 square - feet. Total cost = 234×98 = $22932.

Answer:

1. b. $26,600
2. a. $21,420
3. c. $22,932
