AB = 80 m, BC = 60 m
DF = 50 m, GE = 50 m
HE = 100 m
The area of the triangular region FDE is:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 1250 m2
The area of a triangle is half the base times the height. In triangle FDE (shaded) the base is DF, and the height is GE, because EG meets FD at a right angle.
Base DF \(=50\) m, height GE \(=50\) m
Area \(=\frac{1}{2}\times50\times50=1250\) m2
