Answer:
7600 sq. yd.
Explanation:
Formula for the 'Area of a triangle' is:
1/2 * base * height
The area of the triangle is:
A = 1/2 * b * h
A = 1/2 * 300 * 40
A = 150 * 40
A = 6000
Formula for the 'Are of a square' is:
Length squared
The Are of the square is:
A = L * L
A = 40 * 40
A = 1600
Then we can add it together:
A = 6000+1600
A = 7600 sq. yd.
