step 1
Find the area of the given wall

step 2
we know that
You can paint 75 square feet of a surface every 45 minutes
so
using proportion
Find out how long it takes you to paint a surface area of 42 square feet

That's the easily recognizable factored form of

x² - 16 .
It does not represent it because you have to evenly divide 60 cans into 10 rows.
