Answer:
24 inches squared
Step-by-step explanation:
You know the one side of the 42 region is 6, so divide 42/6 to get 7.
Now you know one side of the 35 region, so 35/7 is 5.
Then, you know one side of the 20 region, so 20/5 is 4.
That gives you the missing side you need to find the area of the shaded region.
6 x 4 = 24 in^2
