In the figure above, |CD| is the base of the triangle CDE. Find the area of the figure to the nearest whole number.

Answer Details

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${}^2$
