The best way to do this is to make up values for the sides.
Say the lengths of square B's sides are each 4 cm. That means A's sides are 2 cm.
So, the area of square B is 4^2 = 16 cm^2, and A's area is 4 cm^2. We can see the shaded area is half of A, so it's 2 cm^2.
What percent of 16 is 2?
2 / 16 * 100 = 12.5%
I believe its 21 sorry if im wrong
So I think it’s 6:2 bc 6 apples and two oranges make 8 so the 8 pieces of fruit are the apples and oranges meaning that it probably put that to throw you off
Answer:
81
Step-by-step explanation:
So first find the are of the rectangle: 9 * 15 = 135
Next find the area of the trapezoid.

135 - 54 = 81
5 because if you plug in to get the equation 3x+20=7x then subtract 3x from both sides and divide by 4 from both sides
