(asap worth 10 points) 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.
72.5 in
75.5 in
83 in
96 in

83 in²

Step-by-step explanation:

To calculate, add the areas of all three shapes that make up the polygon.

Area of rectangle = L×W = 5×8 = 40 in².

Area of top triangle = 1/2×b×h = 1/2×8×7=28 in².

Area of triangle on the right = 1/2×6×5 = 15 in².

Total area = 40+28+15 = 83 in²

both equations and proportions are better.

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
