Answer & Solution
Correct Answer:
Option
A
Since (20)2 + (21)2 = (29)2
So, it is a right-angled triangle with base = 20 m and height = 21 m
∴ Area = $$\left( {\frac{1}{2} \times 20 \times 21} \right)$$ m2 = 210 m2
So, it is a right-angled triangle with base = 20 m and height = 21 m
∴ Area = $$\left( {\frac{1}{2} \times 20 \times 21} \right)$$ m2 = 210 m2
