Hello everybody, a few days ago we started our next unit for math. Square Roots and the Surface Area. As many of you guys already know, in order to find the surface area we need to know the side length. Square root of area equals to side squared.

To find the area of a square you time lengths by the width.

**Square Root**

The answer of a number timed itself.

**Perfect Square **

For example, 36 is a perfect square because 6 times itself equals to 36.

A square root is the factor of a perfect square number, so 7 is the square root of 49. Remember that only the area of a square can be use to find the square root. Use square roots will not help you find the side lengths of a rectangle for example.
