Example Question #11 : Rectangles
Note: Figure NOT drawn to scale.
Refer to the above diagram. Give the perimeter of the red polygon.
The perimeter cannot be determined from the information given.
Since opposite sides of a rectangle have the same measure, the missing sidelengths can be calculated as in the diagram below:
The sidelengths of the red polygon can now be added to find the perimeter:
Example Question #74 : Plane Geometry
The width of a rectangle is , the length is , and the perimeter is 72. What is the value of ?
Start with the equation for the perimeter of a rectangle:
We know the perimeter is 72, the length is , and the width is . Plug these values into our equation.
Multiply and combine like terms.
Divide by 18 to isolate the variable.
Simplify the fraction by removing the common factor.
Example Question #41 : Quadrilaterals
Note: Figure NOT drawn to scale.
Refer to the above diagram. Give the ratio of the perimeter of the large rectangle to that of the smaller rectangle.
The correct answer is not given among the other choices.
Opposite sides of a rectangle are congruent.
The large rectangle has perimeter
.
The smaller rectangle has perimeter
.
The ratio is
; that is, 12 to 5.
Example Question #41 : Quadrilaterals
What is the perimeter of a rectangle with a width of 3 and a length of 10?
26
13
60
30

The formula for the perimeter of a rectangle is .
Plug in our given values to solve:
Example Question #81 : Plane Geometry
Rectangle ABCD has an area of . If the width of the rectangle is , what is the perimeter?
The area of a rectangle is found by multiplying the length times the width. The question tells you the width is and the area is .
Thus the length is 8. .
To find the perimeter you add up all of the sides.
Example Question #2 : How To Find The Perimeter Of The Rectangle
If the perimeter of a rectangle is inches and the width is inches, what is the length?
The perimeter of a rectangle is represented by the following formula, in which W represents width and L represents length:
Given that the width is inches and that the perimeter is inches, the following applies:
Next, subtract from each side.
Now, divide each side by .
This gives us
Example Question #82 : Plane Geometry
A rectangle has an area of . The length of each side is a whole number. What is NOT a possible value for the rectangle's perimeter?
Since each side is a whole number, first find the whole number factors of . They are and , and , and , and and . These sidelengths correspond to perimeters of , , , and , respectively. Thus, is answer.
Example Question #311 : Ssat Middle Level Quantitative (Math)
Give the perimeter of the above rectangle in centimeters, using the conversion factor centimeters per yard.
The perimeter of the rectangle is yards. To convert this to centimeters, multiply by the given conversion factor:
centimeters.
Example Question #312 : Ssat Middle Level Quantitative (Math)
Find the perimeter of the rectangle shown below
The perimeter of a rectangle, or any shape, is the distance around the outside. You add up the length of each side to find this number. The coordinates of the points are . You need to find the distance between each point. The short side is units, and the longer side is units.
Example Question #83 : Plane Geometry
Steve's bedroom measures 20' by 18' by 8' high. He wants to paint the ceiling and all four walls using a paint that gets 360 square feet of coverage per gallon. A one-gallon can of the paint Steve wants costs $36.00; a one-quart can costs $13.00. What is the least amount of money that Steve can expect to spend on paint in order to paint his room?
Two of the walls have area ; two have area ; the ceiling has area .
Therefore, the total area Steve wants to cover is
Divide 968 by 360 to get the number of gallons Steve needs to paint his bedroom:
Since , Steve needs to purchase either two gallon cans and three quart cans, or three gallon cans.
The first option will cost him ; the second option will cost him . The latter is the more economical option.
