b. 61.75
Step-by-step explanation:
Split it into a rectangle and a triangle
1. Rectangle
You can see that the side lengths are 7 and 6.5, so the area is 7 * 6.5 = 45.5
2. Triangle
You know that the base is 6.5 and that the height is 5 (because 12 - 7 = 5) so you can find the area by doing 6.5 * 5 / 2 = 16.25
3. Total
Add the two areas, so 45.5 + 16.25 = 61.75
