Answer:
Option A, 5/8 - 6/8
Step-by-step explanation:
<u>Step 1: Find a common denominator</u>
5/8 is good
3/4 -> 3*2 / 4*2 -> 6/8
<u>Step 2: Combine</u>
5/8 - 3/4 is now 5/8 - 6/8
Answer: Option A, 5/8 - 6/8
Step 1) Divide the figure into separate shapes
Large rectangle: 8 x 9
Medium rectangle: 4 x 6
Quarter circle: r = 3
Step 2) Find the area of each shape
Large rectangle: A = 8 x 9 = 72
Medium rectangle: A = 4 x 6 = 24
Quarter circle: A = 1/4 x 3.14 x 3^2 = 7.065 + 3 = 10.065
Step 3) Add the areas together
A = 72 + 24 + 10.065 = 106.065 square millimeters (may need to round to 106.07, but rounding not given in the problem)
Hope this helps! :)
