An artist lays down a white triangular background on a building on which she will paint a Penrose triangle. The triangular area measures 20 ft on each side and will be covered with three layers of primer paint. a. To the nearest square foot, what is the area of the triangular region to be primed? b. If primer paint covers 200 ft 2 /gal , how many gallons of primer must be purchased?
