In the figure above, |CD| is the base of the triangle CDE. Find the area of the figure to the nearest whole number.
Attached Figure / Diagram
A
56 cm\(^2\)
B
24 cm\(^2\)
C
42 cm\(^2\)
D
34 cm\(^2\)
Verified Correct Answer: D.
Step-by-Step Mathematical Solution
Area of rectangle ABCD = length x breadth
= 7 x 4
= 28 cm\(^2\)
Area of triangle CDE = \(\frac{1}{2}\) base x height
= \(\frac{1}{2} \times 3 \times 4\)
= 6 cm\(^2\)
Area of the figure = 28 cm\(^2\) + 6 cm\(^2\)
= 34 cm\(^2\)
