If you know the area of the square is 256 and the area of the circle is 200.96 you subtract 200.96 from 256 and you get 55.04 is the area of the square that is not covered by the circle. so 55.04/256 because that will give you the percent of the area that is outside that circle but inside the square and you get .215 or 21.50%

Answer by JKismyhusbandbae: 56 + 8x
Explanation: The distributive property says that the product of a number and a sum is equal to the sum of the individual products of the addends and the number. Using this information, multiply the value outside of the parentheses by each of the factors in the parentheses to write the equivalent equation.
There are four rectangles and 2 squares.
Let’s start with the four rectangles.
4 [ 2x(x)]
4 [ (2*7)(7)] = 392 cm^2
______________
Next, let’s find the SA for the two squares.
2 [(2x)^2]
** I need to be clear that both the 2 and the x in the parentheses are squared because the square, of course, is a “perfect square”. This was probably obvious and needless to say, haha oh well.
Next step: plug in values
2 [ [2(7)]^2 ] = 392 cm^2
TOTAL: 392+392 = 784 cm^2
Wow I should have realized the the 4 rectangles are the area as the two squares.
Good luck to you!
