Answer:
192 SQUARE FEET
Step-by-step explanation:
Area of a triangle= 1/2 ×base×height
1/2 of the base =32/2 ft
=16 ft
Let the height be A ft and another side(16 ft) be B ft
We know that, A^2 + B^2 =Hypotenuse^2
OR, A^2 + 16^2 = 20^2
OR, A^2= 400-256
OR, A^2 =144
OR, A= Square root of 144
OR, A=12 ft
By the problem,
1/2 ×Base×Height =Area of half of the triangle
1/2 ×16×12= Area of half of the triangle
96=Area of half of the triangle
AREA OF THE TRIANGLE=96 ×2
AREA OF THE TRIANGLE=192 SQUARE FEET.
