The area of A, B and C are 54, 3 and 21 square units respectively
<h3>Surface area of a figure</h3>
Surface area of the given figure is the sum of the shapes of the given diagram.
The diagram contains 2 rectangles and 1 triangle. Find the area of the rectangle.
<h3>Area of rectangle A = length * width</h3>
Area of rectangle A = 6 * 9
Area of rectangle A = 54 square units
For the triangle B;
Area of triangle C = 1/2 *3 * 2
Area of triangle C = 3 square units
For rectangle C
Area = length * width
Area of C = 7 * 3
Area of C= 21 square units
Hence the area of A, B and C are 54, 3 and 21 square units respectively
