In the figure above, |CD| is the base of the triangle CDE. Find the area of the figure to the nearest whole number.
-
A.
56 cm(^2) -
B.
24 cm(^2) -
C.
42 cm(^2) -
D.
34 cm(^2)
Correct Answer: Option D
Explanation
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)
