What is the area of a square if one side of the square is 6?
What is the area of a square if one side of the square is 6?
If one side of a square is 6, then each of the four sides of the square are equal to 6. To find the area of a square, we multiply the length and the height together. The length is 6, and the height is 6, thus the equation we use is 
.
Remember the formula for the area of a quadrilateral is 
. For a square, one side is equal to both the length and the width.

James found the area of the square below to be 36 centimeters squared.
What is the length of one side of the square?
James found the area of the square below to be 36 centimeters squared.
What is the length of one side of the square?
The area of a square can be found by multiplying the length of a side by itself. 36 is equal to 6 times 6, therefore the length of one side is 6 centimeters.
