Question

Blake mows a half acre of lawn for his grandparents every two weeks. If Blake has already mowed three-fifths of the lawn, how many more square feet must he mow?

Answer 1

Answer:

Blake still has to mow 17,424 acres.

Given:

There are 43,560 square feet in an acre. 

So:

Blake has already mowed 60% of the lawn.

Note: Leaving him 40% more to mow.

All we have to do is:

$\implies$ Multiply 43560 by 0.4

In order to find:

The number of square feet remaining.

So: $\boxed{\sf{43560 \times 0.4 = 17424}}$

Final answer: 17424
