kaheart [24]

This question is asking if the paint will be able to cover the area of the figure stated. (16 ft wide and 12 ft high i.e width and length.) Since one gallon covers 250 ft, using the area (A=w*l) formula, we can find the figure's area.

A= 16*12

A=192ft^2

Carolyn can cover the wall.

Hope this helps!
