Answer:
152 m^2
Explanation:
Find the area of the triangle and subtract it from the area of the square
area of half-triangle = 1/2 x base x height = 1/2 x 8 x 13 = 52
since that's for half of the triangle we times it by 2 to get the whole triangle so 104.
area of the square = 16 x 16 = 256
area of shades region = 256 - 104 = 152 m^2
