Question

NUMBER 7- The area of the square at
right is 100 square units.
Find the value of x.

Answer 1

Answer: x = 8

Explanation:

`(x+2)^2=100`

`\sqrt[]{(x+2)^2}=\sqrt[]{100}`

`x+2=10\\x=10-2\\x=8`

Answer 2

8

Explanation:

all sides must be equal since this is a square and since we know the area is 100 then that means both sides will have to add up to 10 because 10 times 10 equals one hundred therefore the answer is 8
