Question

Find the area of the given figure, given that the area of the triangular region is 18 sq. units.

• A. 70 sq. units
• B. 72 sq. units
• C. 75 sq. units
• D. 68 sq. units

Answer 1

The correct option is B

72 sq. units

The given figure can be considered as the combination of a triangle and rectangle.
From the figure,
Length of the rectangle = 9 units
Breadth of the rectangle = 6 units
Now, area of the given figure = area of the triangle + rectangle
$\Rightarrow$ Area of the given figure = 18 + length $\times$ breadth
$\Rightarrow$ Area of the given figure = 18 + 9 $\times$ 6
$\Rightarrow$ Area of the given figure = (18 + 54) sq units = 72 sq units
