The Area of A Quadrilateral Given A Square 1. The problem statement, all variables and given/known data In a square PQRS, point T is the midpoint of side QR. If the area of square PQRS is 3, what is the area of quadrilateral PQTS? 2. Relevant equations area = 1/2 base * height 3. The attempt at a solution Side QR = 1.737 Side RS = 1.737 TR = .8685 area = 1/2(1.737) * .8685 = .25 The area of the triangle = .25 3 - .25 = 2.75 The area of quadrilateral PQTS = 2.75 Is my answer right?
