Example Questions
Example Question #21 : Plane Geometry
Find the area of the square shown below:
A square has sides that are all equal. Area is length times width, and in the case of a square it is the side measurement times itself. 
Example Question #22 : Geometry
Use the following to answer the question.
Find the area of the square.
To find the area of a square, we use the following formula:
where l is the width and w is the width of the square.
If we look at the square
we can see the width is 7in. Because it is a square, we know that all sides are equal. Therefore, the length is also 7in. Knowing this, we can substitute into the formula. We get
Example Question #22 : Squares
Use the following square to answer the question:
Find the area.
To find the area of a square, we will use the following formula:
where l is the length and w is the width of the square.
Now, let's look at the square.
We can see the width of the square is 2in. Because it is a square, all sides are equal. Therefore, the length is also 2in.
Knowing this, we can substitute into the formula. We get
Example Question #23 : Squares
Use the following square to solve the problem:
Find the area.
To find the area of a square, we will use the following formula:
where l is the length and w is the width of the square.
Now, given the square
we can see the length is 5cm. Because it is a square, all sides are equal. Therefore, the width is also 5cm. So, we can substitute
Example Question #22 : Plane Geometry
What is the perimeter of a square of area 36?
The area of a square is the square of the length of its side (all sides are equal in a square). If the area is 36, then the length of each side is 6.
The perimeter of a square is 4 times the length of its side. Therefore, 4 times 6 is 24.
Example Question #23 : Plane Geometry
Which of the following is NOT a quadrilateral?
nonagon
parallelogram
rhombus
trapezoid
nonagon
Quadrilaterals have 4 sides. A nonagon has 9 sides.
Example Question #24 : Plane Geometry
What is the perimeter of a square that has a side measuring 3 inches in length?
Perimeter is the sum of all the sides. For a square, 
Therefore, for this square,
Example Question #25 : Plane Geometry
What is the perimeter of a square that has a side measuring 1 inch in length?
Perimeter is the sum of all the sides. For a square,
Therefore, for this square,
Example Question #26 : Plane Geometry
What is the perimeter of the square?
To find the perimeter of this square, add all four sides together. Even though we are only given one side's length, every side of a square always has the same length!
Example Question #27 : Plane Geometry
What is the perimeter of the square?
To find the perimeter of a square, simply add all four sides together. Even though we are only given one side's length, squares always have four, equal sides!
