2 * 5 1/2 = 11
I need at least 20 characters so I guess I'll break it down in 2 parts:
2 * 5 = 10
2 * 1/2 = 1
10 + 1 = 11
There ya go :)
Answer:
centre (5,0)
radius:9
I hope it will be helpfulness
I think the answer is 15x^4y^5z^2
First, by using the distance formula for just one side, we can find the length of all sides (a square has 4 equal sides.) Then, we can apply the area of a square formula, which is a^2.
Distance formula:

√((-2 + 5)^2 + (-8 + 4)^2)
√((3)^2 + (4)^2)
√9 + 16
√25
5
The side lengths of the square are each equal to 5, and by applying the formula for area, we can find the area of the square.
5^2 = 25
<h3>The area is 25.</h3>
