Example Questions
Example Question #1211 : Isee Lower Level (Grades 5 6) Quantitative Reasoning
What is the length of a rectangular room with a perimeter of 
We have the perimeter and the width, so we can plug those values into our equation and solve for our unknown.
Subtract 
Divide 
Example Question #573 : Plane Geometry
Find the perimeter of the rectangle shown below:
The perimeter of a rectangle is all of the sides added together. When you have a rectangle the opposite sides are also the same lengths, so even when they aren't labeled you know the measurements of the other sides.
Example Question #142 : How To Find The Perimeter Of A Rectangle
Use the following to answer the question.
Find the perimeter of the rectangle.
To find the perimeter of a rectangle, we use the following formula:
where a, b, c, and d are the lengths of each side of the rectangle.
When we look at the rectangle
we know that the length is 9ft and the width is 4ft. Because it is a rectangle, we also know the lengths of the unmarked sides. The unmarked sides are equal to the length of the opposite side. So, we can substitute this into the formula. We get
Example Question #511 : Rectangles
Find the perimeter of the rectangle.
A rectangle has a length of 12cm and a width of 4cm. What is the perimeter of this rectangle.
To find the perimeter of a rectangle, you must first understand that a rectangle's opposite sides are equal. Therefore if you know the length of one side it is the identical length of the opposite side.
32cm is your answer.
Example Question #512 : Rectangles
Find the perimeter of a rectangle.
A rectangle has a width of 7cm and a length of 10cm. What is the perimeter of the rectangle?
First you need to understand that opposite sides of a rectangle are equal. Then you are able to add the value of each side to itself and then add your sums together to get the perimeter of a rectangle.
Example Question #581 : Geometry
Use the following rectangle to answer the question:
Find the perimeter.
To find the perimeter of a rectangle, we will use the following formula:
Where a, b, c, and d are the lengths of the sides of the rectangle.
Now, let's look at the rectangle.
We can see the length is 6in. Because it is a rectangle, the opposite side is also 6in.
We can also see the width of the rectangle is 3in. Because it is a rectangle, the opposite side is also 3in.
Knowing this, we can substitute into the formula. We get
Example Question #581 : Plane Geometry
Use the following rectangle to solve the problem:
Find the perimeter.
To find the perimeter of a rectangle, we will use the following formula:
Where a, b, c, and d are the lengths of the sides of the rectangle.
Now, given the rectangle
we can see the length is 11in. Because it is a rectangle, the opposite side is also 11in.
The width is 5in. Because it is a rectangle, the opposite side is also 5in.
So, we can substitute.
Example Question #582 : Geometry
What is the width of the rectangle if the perimeter is 
The formula for perimeter of a rectangle is
To solve for the width we can plug our known values into the equation.
Subtract 
Divide 
Example Question #81 : Apply Area And Perimeter Formulas For Rectangles: Ccss.Math.Content.4.Md.A.3
What is the length of a room with a perimeter of 
We have the perimeter and the width, so we can plug those values into our equation and solve for our unknown.
Subtract 
Divide
Example Question #5741 : Ssat Elementary Level Quantitative (Math)
Emily is digging a garden in her backyard that is 
The formula for perimeter of a rectangle is
To solve for the perimeter we can plug our known values into the equation.
