Marcus loves baseball and wants to create a home plate for his house. marcus needs to calculate the area of the home plate at the ball field so he can reconstruct it when he gets home. calculate the area of the polygon.

a) 30 in2
b) 31.5 in2
c) 36.5 in2
d) 39 in2

For the answer to the question above,  first you must find the area of the rectangle, which is 3 × 6 = 18 inches squared. Then, you find the area of the triangles. To find the area of the top triangle, you'd do base × height/2 (5 × 6)/2 = 15 inches squared. The triangle on the left would be (4 × 3)/2 which is 6 inches squared. After you've added up all of the values, you get (18 + 15 + 6) = 39 inches squared
