Example Question #71 : Squares, Rectangles, And Parallelograms
Find the area of a square with a width of 11in.
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, we know the width of the square is 11in. Because it is a square, all sides are equal. Therefore, the length is also 11in.
So, we will substitute. We get
Example Question #72 : Squares, Rectangles, And Parallelograms
Use the following rectangle to answer the question:
Find the area.
To find the area of a rectangle, we will use the following formula:
where l is the length and w is the width of the rectangle.
Now, given the rectangle
we can see the length is 9cm and the width is 7cm. So, we will substitute. We get
Example Question #362 : 2 Dimensional Geometry
Find the area of a rectangle with a length of 12in and a width that is half the length.
To find the area of a rectangle, we will use the following formula:
where l is the length and w is the width of the rectangle.
Now, we know the length of the rectangle is 12in. We know the width of the rectangle is half the length. Therefore, the width is 6in. Now, we can substitute. We get

Example Question #73 : Squares, Rectangles, And Parallelograms
What is the area of a square that has a perimeter of ?
Start by finding the length of a side for the square by using the given perimeter.
For the given square,
Now, recall how to find the area of a square:
Plug in the side length of the square to find its area.
Example Question #74 : Squares, Rectangles, And Parallelograms
Use the following rectangle to answer the question:
Find the area.
To find the area of a rectangle, we will use the following formula:
where l is the length and w is the width of the rectangle.
Now, given the rectangle
we can see the length is 9cm and the width is 7cm. So, we substitute. We get
Example Question #75 : Squares, Rectangles, And Parallelograms
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, given the square
we can see the width is 8cm. Because it is a square, all sides are equal. Therefore, the length is also 8cm. So, we can substitute. We get
Example Question #76 : Squares, Rectangles, And Parallelograms
Find the area of a rectangle with a length of 15in and a width that is a third of the length.
To find the area of a rectangle, we will use the following formula:
where l is the length and w is the width of the rectangle.
Now, we know the length of the rectangle is 15in. We know the width is a third of the length. Therefore, the width is 5in. So, we can substitute. We get
