Options:
A) $ 252m^{2} $
B) $ 156m^{2} $
C) $ 96m^{2} $
D) $ 1152m^{2} $
Show Answer
Answer:
Correct Answer: A
Solution:
- [a] Area of the field = Area of $ \Delta ABD $ + Area of $ \Delta BDC $ $ =\frac{1}{2}\times 24\times 8+\frac{1}{2}\times 24\times 13 $ $ =\frac{1}{2}\times 24\times (8+13) $ $ =12\times 21=252m^{2} $
