diameter of a circle = 2*radius or circumference/pi
L=1.5w It means that there is always a constant ratio, which is 1 1/2 between the length and the width. So if you know the dimension of either one, you can calculate the dimension of the other. Example: Suppose that the width = 10. Now you can calculate that the length = 15. Second example: What is the width if the length is 45? Now use the relationship given to calculate that the width is 30.
length x width = area
length * width
If the room is rectangular, the area is the product of its length and width.
the formula for area of a square is length times width
To calculate the length when you have both the width and the area, you can use the formula for the area of a rectangle: Area = Length × Width. Rearranging this formula to solve for length gives you Length = Area ÷ Width. If you only have the width and length, you can directly use the length value provided.
To calculate volume simply do length x width x height
You can calculate the volume by multiplying height, width, and mass. Then, divide the mass by the density to find the volume. Finally, calculate the length by dividing the volume by the height and width.
By multiplying its length to its width. Area= length x width
Because the perimeter is lenght + length +width +width, you do perimeter - double the width, and then halve the remaining number. that should give you the length.
The perimeter of a rectangle is the distance around the rectangle. The area of a rectangle is the space inside the rectangle. To calculate either one you need the length and the width of the rectangle. To calculate the area multiply the length times the width. To calculate the perimeter add the length+width+length+width (that is the distance all the way around)
The width could be virtually anything. If you are wanting to find out how to calculate width, you need to have more information in addition to length.
length, width X height.
Length times width.
L=1.5w It means that there is always a constant ratio, which is 1 1/2 between the length and the width. So if you know the dimension of either one, you can calculate the dimension of the other. Example: Suppose that the width = 10. Now you can calculate that the length = 15. Second example: What is the width if the length is 45? Now use the relationship given to calculate that the width is 30.
To calculate area, or cm2, the length and width must be multiplied. For example, a length of 2 cm and a width of 3 cm equals an area of 6 cm.
To calculate the area of a rectangle :- Measure the length. Measure the width. Multiply the length by the width - the product is the area. EXAMPLE : length = 7 inches, width = 3 inches, Area = 7 x 3 = 21 square inches.
