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 : Squares
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 #4 : 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 : Squares
Michaela drew th square below.
What is the area of the square?
100 square centimeters
12 square centimeters
112 square centimeters
144 square centimeters
48 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.
Example Question #6 : Squares
James found the area of the square below to be 36 centimeters squared.
What is the length of one side of the square?
6 centimeters
9 centimeters
18 centimeters
8 centimeters
36 centimeters
6 centimeters
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.
Example Question #7 : Squares
Daphne found the area of the square below to be 81 centimeters squared.
What is the length of one side of the square?
9 centimeters
7 centimeters
20 centimeters
8 centimeters
81 centimeters
9 centimeters
The area of a square can be found by multiplying the length of a side by itself. 81 is equal to 9 times 9, therefore the length of one side is 9 centimeters.
Example Question #8 : Squares
If the area of a square is , what is the length of each side?
To find the area of a square, the length must be multiplied by the height. Since a square has four equal sides, the length and width will have the same measurement. We must, therefore, find the square root of . Since , is the square root of , which makes it the measurement for both the length and the width of the square.
Example Question #7 : Squares
If the length of a rectangle is four times the width, and the width is , what is the perimeter of the rectangle?
In order to find the perimeter of a rectangle, we must add the length of all the sides together. In this case, however, we must first determine the length, which can be found by multiplying by , because the length is four times the width, which had already been defined as .
Now we add together the four sides.
Example Question #9 : Squares
If the perimeter of a square is , what is the length of each side?
To find the perimeter of a square, all the sides must be added together. Since a square has equal sides, the length of each side can be determined by dividing the perimeter () by .
