Example Questions
Example Question #42 : Geometry
If a rectangle has an area of 18, which of the following are possible dimensions of the length and width?
None of these
If the area of the rectangle is 18, that means that the length and the width, when multiplied together, should equal 18.
The only numbers from the answer choices that would result in the product of 18 are 9 by 2, which is therefore the correct answer.
Example Question #12 : How To Find The Area Of A Rectangle
Ben is making a sandbox with a width of 4 feet and a length of 6 feet. What is the area of the sandbox?
The area of a rectangle is the width times the length.
The width is 4 feet and the length is 6 feet. Because 4 times 6 is 24, the area is 24 square feet.
Example Question #13 : How To Find The Area Of A Rectangle
Jerry has a mat with an area of 20 square feet and a length of 5 feet. What is the width of the mat in inches?
None of these
The area of a rectangle is the width times the length.
Given that the area is 20 square feet and the length is 5 feet, the width would have to be 4 feet because 5 times 4 is 20.
Given that the question asks for the width in inches, 4 should be multiplied by 12 (as there are 12 inches in a foot).
This gives us a product of 48 inches, which is the width.
Example Question #981 : Isee Lower Level (Grades 5 6) Mathematics Achievement
If the length of a rectangle is 2r and the width of the rectangle is 3w, what is the area?
The area of a rectangle is found by multiplying the length by the width. Given that the length is 2r and that the length is 3w, the area will be the product of those numbers, which is .
Example Question #982 : Isee Lower Level (Grades 5 6) Mathematics Achievement
A rectangle has a length of 10 feet and a width of 1 foot. What is the area of the rectangle?
The area of a rectangle is calculated by multiplying the length by the width.
Given that the length is 10 feet and that the width is 1 foot we can multiply to find the final area:
Example Question #983 : Isee Lower Level (Grades 5 6) Mathematics Achievement
What is the area of a rectangle with a width of 6 inches and a length of 7 inches?
The area of a rectangle is equal to the length multiplied by the width. Since the width is 6 inches and the length is 7 inches, the area is equal to 6 times 7.
The area is 42 square inches.
Example Question #984 : Isee Lower Level (Grades 5 6) Mathematics Achievement
If a rectangle has a perimeter of 40, a width of 4, and a length of 4x, what is the value of x?
The perimeter of a rectangle is equal to .
Thus, .
Add like terms:
Subtract 8 from both sides:
Divide both sides by 8:
Example Question #22 : How To Find The Area Of A Rectangle
A rectangle has a perimeter of 30. One of its sides has a length of 6. What is its area?
If the rectangle has one side that is , we know that two of them must be that size. Therefore, we know that it looks something like this:
If the perimeter is 30, you know that the following equation holds:
This means that the other two sides can be found by solving for :
The area of a rectangle is equal to its base times its height:
Example Question #22 : How To Find The Area Of A Rectangle
A rectangle has two sides that are each . Its other sides are twice this length. What is the area of the rectangle?
If one side is , the doubled side must be . Therefore, the rectangle looks like this:
The area of a rectangle is equal to its base times its height:
Example Question #985 : Isee Lower Level (Grades 5 6) Mathematics Achievement
What is the area of the following rectangle?
The area of a rectangle is defined as the base multiplied by its height. Therefore, for this rectangle:
