First you are going to look at the smallest box and figure out what the area is once you do that you will need to find the area of the bigger box once you figure out both of the areas you will then find out what they are you will then add up the amounts to get the area of both squares together
The formula for a circumference of a circle is 2πr
2 × π × 25 = 157
so your answer is A 157in.
