Answer: 192 square units
Explanation:
Formula: Area of rectangle = Length x width
Area of triangle = 0.5 x base x height
Given: A quadrilateral is made up of one rectangle and two right triangles.
Rectangle has a height of 12 units and a length of 12 units.
So, Area of rectangle = 12 x 12 = 144 sq. units
Triangle has a height of 12 units and a base of 4 units.
Area of triangle = 0.5 x 12 x 4 = 24 sq. units
Total area of quadrilateral = Area of rectangle + 2 (Area of triangle)
= 144+ 2(24)
=144+48
= 192 sq. units
Hence, the correct option is 192 square units
