Example Question #1 : Rectangles
Which of the following is equal to the area of a rectangle with length 250 centimeters and width 140 centimeters?
Divide each dimension by 100 to convert centimeters to meters:
Multiply length by width:
square meters
Example Question #3 : Rectangles
A hectare is a unit of area equal to 10,000 square meters.
A rectangular plot of land measures 1,400 meters by 800 meters. Give the area of this plot in hectares.
Multiply length times width to get the area in square meters:
square meters
Divide by 10,000 to convert to hectares:
hectares
Example Question #5 : Rectangles
Which of the following is equal to the area of a rectangle with length 27 inches and width 15 inches?
Divide each dimension by 12 to convert from inches to feet:
Multiply length by width:
square feet
Example Question #11 : Rectangles
Which of the following is equal to the area of a rectangle with length feet and width feet?
Multiply each dimension by 12 to convert from feet to inches:
Now multiply this length and width to get the area:
Example Question #171 : Plane Geometry
A rectangular prism has length 24 inches, width 18 inches, and height 15 inches. Give its surface area in square feet.
Divide each dimension in inches by 12 to convert from inches to feet:
feet
feet
feet
Now, substitute in the surface area formula:
Example Question #62 : Quadrilaterals

So we can write:
Example Question #104 : Plane Geometry
The length of a rectangle is three times longer than its width. If the width of the rectangle is meters, give the area of the rectangle.
The length of the rectangle would be:
We know that:
where:
So we can write:
Example Question #173 : Plane Geometry
Which of the following is the area of a rectangle with a width of 4 feet and a length that is twice the width?
The area of a rectangle is found by multiplying the width by the length.
We know that the width is 4 feet and the the length must be twice the width. Multiply the width by 2 to find the length.
Multiply the length and width to find the area.
