Two figures are arranged as shown. Which of the following can be used to find the area of the figure shaded light gray.

Answer:
9² − x²
x(9-x)+9(9-x)
Step-by-step explanation:
The area of the shaded light gray square =
= the area of the whole square - the area of the shaded dark gray square
= 9² - x²
since x(9-x)+9(9-x) = 9x - x² + 9² - 9x = 9² - x²
then x(9-x)+9(9-x) is also a right answer.
Answer:
The answer is 9² - x² and x(9 - x) + 9(9 - x)
Step-by-step explanation:
Here, In a Figure, two square is given first which is small and shaded dark gray and second which is big and shaded light gray.
Now, For area of Small Square.
Length (l) = x
A = l²
A = (x)²
A = x²
Now, For area of Big Square.
Length (l) = 9
A = l²
A = (9)²
A = 81
Then, To find are of Shaded light gray square
Area of Big Square - Area of Small Square.
9² - x²
Thus, The answer is 9² - x² and
x(9 - x) + 9(9 - x)
