- 13,068 = 21,780 - 13,068 = 8,712 square feet

Answer 2

Answer: Blake still has to mow 17,424 acres.

There are 43,560 square feet in an acre. 

Blake has already mowed 60% of the lawn, leaving him 40% more to mow.

All we have to do is multiply 17,424 by 0.4 to find the number of square feet remaining.

43560 x 0.4 = 17424
