Example Question #61 : Squares, Rectangles, And Parallelograms
Find the area of a rectangle with a width of 7in and a length that is three times the width.
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 width of the rectangle is 7in. We also know the length is three times the width. Therefore, the length is 21in. So, we can substitute. We get
Example Question #61 : Squares, Rectangles, And Parallelograms
A square has an area of 
A square has 4 equal sides. The formula to find the area of a square is
where b is the length of one side of the square. To find the length of one side of the square, we will solve for b.
Now, we know the area of the square is 
Therefore, the length of one side of the square is 14cm.
Example Question #63 : Squares, Rectangles, And Parallelograms
What of the following is NOT a property of a quadrilateral?
A quadrilateral is a shape with four corners, or vertices, whose interior angles angles must sum up to 360 degrees.
The shape also has 4 edges.
The quadrilateral does not necessarily require two pairs of parallel lines.
Quadrilaterals may also be irregular.
The answer is:
Example Question #62 : Squares, Rectangles, And Parallelograms
Find the area of a square with a width of 7cm.
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 7cm. Because it is a square, all sides are equal. Therefore, the length is also 7cm. So, we can substitute. We get
Example Question #352 : Geometry And Graphs
Find the area of a rectangle with a length of 6in 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 6in. We also know the width of the triangle is a third of the length. Therefore, the width is 2in. So, we substitute. We get
Example Question #1322 : Ged Math
A square has an area of 
A square has 4 equal sides. The formula to find the area of a square is
where b is the length of one side of the square. To find the length of one side of the square, we will solve for b.
Now, we know the area of the square is 
Therefore, the length of one side of the square is 12cm.
Example Question #1323 : Ged Math
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.
So, given the rectangle
we can see the length is 6in and the width is 3in. So, we can substitute. We get
Example Question #1324 : Ged Math
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 length is 14cm. Because it is a square, all sides are equal. Therefore, the width is also 14cm. So, we can substitute. We get
Example Question #21 : Area Of A Quadrilateral
Find the area of a square with a perimeter of 
A square has four equal sides.
This means that each side is one fourth of the perimeter.
Write the area of a square.
The answer is:
Example Question #361 : 2 Dimensional Geometry
Find the area of a square with a perimeter of 
To find the length of one side, we will need to divide the perimeter by 4, since a square has four equal sides.
The area of a square is:
Square the quantity of the side.
Use the FOIL method to solve.
The answer is:
