What is the area of the composite figure whose vertices have the following coordinates? (−1, 5) , (3, 5) , (7, 3) , (3, 0) , (−1, 1) Enter your answer in the box. units²
We can see the figure as two triangles and a square. We have then: Area of the square: A1 = (4) * (4) A1 = 16 Area of the small triangle: A2 = (1/2) * (4) * (1) A2 = 2 Area of the big triangle: A3 = (1/2) * (5) * (4) A3 = 10 The area of the figure is: At = A1 + A2 + A3 At = 16 + 2 + 10 At = 28units² Answer: The area of the figure is: At = 28units² Note: see attached image
