Me and fast! the picture is included!

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

So first you'd 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, which is your answer. I hope this helps!

The answer is a good luck

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
