Answer:
<em>On day the he covers </em>128.4 ft²
<u>Step-by-step explanation</u>:
Lets first figure out how much he has done so far
To figure out how much he does we can use a proportion
Set up a proportion for first day
2/7 = x/299.6
Solve the proportion
2×299.6÷7 = 599.2/7 = x
x = 85.6
<em>He covered 85.6 sq/ft on day 1</em>
Find day two
85.6 * 2 = 171.2
Find how much is left to do on day 3
299.6-171.2 = 128.4 ft²
