Answer:
36in²
Explanation:
In order to find the area of a composite shape, we must split the shape up into two regular shapes.
Thus, area of composite shape = area of triangle + area of rectangle
The area of a rectangle can simply be found my multiplying the width by the length
The rectangle shown has a length of 9 in and a width of 3 in
Hence, A = 9 * 3
9 * 3 = 27
Therefore the area of the rectangle is 27in²
The area of a triangle can be calculated by multiplying the base length by the height and then dividing the product by 2
The triangle shown has a given height of 2 in and a base length of 9 in
Thus,
![A=(2*9)/(2)](https://img.qammunity.org/2022/formulas/mathematics/college/dfj44sdstdrtno7vyjvlfyuum3fga0s14i.png)
2 * 9 = 18
18 / 2 = 9
Hence, the area of the triangle is 9 in²
Finally we add the two areas together
9 + 27 = 36
Hence, the area of the composite figure is 36in²
