Cesar made a rectangular banner that is 4 feet by 3 feet. he wants to make a triangular banner that has the same area as the other banner. the triangular banner will have a base of 4 feet. what should its height be?

The width of a rectangle is 20 units. can the perimeter p of the rectangle be 64 units when its length x is 11 units? no, because p = 2x + 2(20) no, because p ≠ 2x + 2(20) yes, because p ≠ 2x + 2(20) yes, because p = 2x + 2(20)
