Example Question #1 : Squares
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.
Example Question #2 : Squares
One side of a square is centimeters long. What is the area of the square?
The formula for finding the area of a square is , or, because this is a square, .
area = centimeters centimeters, or
Example Question #3 : How To Find The Area Of A Square
A right triangle has a base of and a height of .
What is the area of the rectangle made by 2 of these triangles aligned along the hypotenuse?
If one combines the 2 identical triangles, their base and height become the length and width of the rectangle.
Area of a rectangle is:
In this case
Example Question #3 : Squares
A square has an area of . What is the length of one side?
You can find the area of a square by multiplying two sides together. All of the sides of a square are equal. In this case, , so the length of all of the sides of the square is 4 inches.
Example Question #5 : How To Find The Area Of A Square
Michaela drew th square below.
What is the area of the square?
144 square centimeters
48 square centimeters
100 square centimeters
12 square centimeters
112 square centimeters
144 square centimeters
The area of a square can be found by multiplying the length of a side times itself. The side length of the above square is 12 cm. By finding 12 x 12, we find that the area of the square is 144 cm. squared.
