The area of the shape is 51 square inches
We are to find the area of the shape given
This kind of shape is a composite shape as it contains two or more shapes fused into it.
To get the area of the shape, we need to get the areas of te individual shape then add them together.
Mathematically, the following shapes are in the given shape;
rectangle that measures 3 in by 13 in ( You can obtain this by closing the gap so that we get a complete rectangle)
Also, we have a rectangle that measures 3 in by 4 in
Mathematically, the area of a rectangle is L * B
The area of the shape is (3 * 13) + (4 * 3)
= 39 + 12 = 51 square inches
