Answer:
D. 11
Step-by-step explanation:
Add all the numbers and divide by 4
12 inches = 1 foot
144 square inches = 1 square foot
1250 square inches = 1250/144 = 8.68 square feet
Distribute on the left side
7.4a+22.2=3.2a+43.2
Subtract 3.2a from both sides
4.2a+22.2=43.2

4.2a=21
Divide both sides by 4.2
a=5
