How do you calculate the dimensions of a rectangle if you know the perimeter and the length?
A rectangle by definition has two pairs of sides with equal length. Since perimeter equals the length of all the sides. The equation for the perimeter of a rectangle could be thought of as: 2L + 2W = P Where L represents the length of one side of the rectangle and W represents the length of the adjacent (next to) side of the rectangle. If you know the length of one side and the perimeter, plug those values in as L and P and then solve for W. That will give you L and W which are the dimensions of the rectangle.

What formula expresses the perimeter of a rectangle in terms of its length?
The formula for the perimeter of a rectangle is: p = 2(l + w) In other words, just add all four sides. You can't calculate the perimeter of the rectangle if you know only the length.
What is the length of a rectangle that its perimeter is 30?
The perimeter of a rectangle is not sufficient to determine its length.
What is the perimeter of the rectangle that is 0.9 square units?
To find the perimeter of a rectangle, you need more information than just the area. The area of a rectangle is calculated by multiplying its length by its width. Without knowing the specific dimensions of the rectangle, it is impossible to determine the perimeter. Additional information, such as the length or width of the rectangle, is required to calculate the perimeter.
The length of a rectangle is 4 cm more than the width If the perimeter of the rectangle is 20 cm what are the dimensions?
length + width = 20/2 = 10 length = 7cm, width = 3cm
What is the area of a rectangle whose perimeter is 136?
If the only information that you have is ... A) the figure is a rectangle, and B) the perimeter ... then you cannot calculate the area. The area of a rectangle is the length multiplied by the height., The perimeter is twice the length plus twice the height. So, a rectangle with a length of 9 units and a height of 1 until will have a perimeter of 20 units and an area of 9 square units. Another rectangle with a length of 6 units and a height of 4 units will also have a perimeter of 20 units, but it will have an area of 24 square units. To be able to calculate the area from the perimeter you need to know one of two additional things - either one of the measurements, or the ratio of the height to the length.
