To find the area of a triangle, we will use the formula:
Area = (1/2) * base * height
In this case, we don't have the height of the triangle, but we can find it using the Pythagorean theorem. We can consider the sides 9in and 7in to be the base and the height respectively. So, the height of the triangle can be found using the Pythagorean theorem:
height^2 + 4^2 = 9^2
height^2 + 16 = 81
height^2 = 65
height ≈ 8.06in
Now, we can calculate the area of the triangle:
Area = (1/2) * 9 * 8.06
Area ≈ 36.27in squared
Therefore, the closest option is 40 inches squared.
