First we have to solve for the area of the wall.
The area of a rectangle is A=l*w
A=l*w
A=28*12
A=336 ft²
So 336 square feet were painted in 5 1/4 hours. How many square feet were painted in one hour?
Given the info, the following equation can be made.
[tex] \frac{5 \frac{1}{4} hour}{336 sq ft}= \frac{1 hours}{x sq feet} [/tex]
Cross multiply
5 1/4x=336
divide both sides by 5 1/4
x=64ft
In one hour, 64 square feet were painted.
Tyler painted 64 square feet per hour
