Question

I need help finding the area of the polygons.

Answer 1

hope it helps

Explanation:

1. area = 15*15 - 5*6 = 195

2. area = (8+16)*8 /2 - 5*3 = 96 - 15 = 81

3. area = 12*3 + 9 * (12 - 4 - 4) = 36 + 9*4 = 36+36 = 72

4. x = 6-3 = 3

y = 3- (-1) = 4

z = 7-3 = 4

area = 2*x*y/2 + y*z = 2*3*4/2 +4*4 = 12+16 = 28
