# Quick Answer: The Length Of A Rectangle Is Twice Its Width. The Perimeter Is 60 Ft. Find Its Area.

## How do we calculate area?

The simplest (and most commonly used) area calculations are for squares and rectangles.

To find the area of a rectangle, multiply its height by its width.

For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area..

## How do you find the length and width if you have the area and perimeter?

Let P be the perimeter of a rectangle and A its area. Let W and L be, respectively, the width and length of the rectangle. Find W and L in terms of P and A. Solve the above equation for L and find W using W = P / 2 – L.

## How do I work out area and perimeter?

Perimeter of a RectangleRemember the formula for perimeter and area of a rectangle. The area of a rectangle is a = length * width, while the perimeter is p = (2 * length) + (2 * width)Substitute the known values into the area formula. 36 = 4 * w. … Substitute values for length and width into the perimeter formula.Aug 5, 2020

## What is the perimeter formula?

Perimeter, Area, and VolumeTable 1 . Perimeter FormulasShapeFormulaVariablesSquareP=4ss is the length of the side of the square.RectangleP=2L+2WL and W are the lengths of the rectangle’s sides (length and width).Trianglea+b+ca,b , and c are the side lengths.2 more rows

## What is a perimeter in math?

Perimeter is the distance around the edge of a shape. Learn how to find the perimeter by adding up the side lengths of various shapes.

## How do you find the length and breadth of a rectangle when given the perimeter and area?

To find Length or Breadth when Area of a Rectangle is givenWhen we need to find length of a rectangle we need to divide area by breadth.Length of a rectangle = Area ÷ breadth.ℓ = A ÷ b.Similarly, when we need to find breadth of a rectangle we need to divide area by length.Breadth of a rectangle = Area ÷ length.b = A ÷ ℓ

## How do I find the length and width of a rectangle if I have the area?

A = L * W, where A is the area, L is the length, W is the width or breadth. NOTE: When multiplying the length by the width, always ensure you work in the same unit of length.

## Is length twice the width?

The question tells us the length is twice the width. That means the length is two times the width. The length is longer. So we’ll use the variable w to stand for whatever the width will be.

## How do you find the dimensions of a rectangle when the perimeter is given?

Find the dimensions of the rectangle using the perimeter. For this example, suppose the perimeter is 22 feet and the length is 5 feet. Write down the perimeter equation for a rectangle: P = 2L + 2W where “P” stands for perimeter, “L” stands for the length and “W” stands for the width.

## How do you find the perimeter calculator?

How to find perimeter – perimeter formulasSquare perimeter formula: P = 4a.Rectangle perimeter formula: P = 2(a + b)Triangle perimeter formulas: … Circle perimeter formula: P = 2πr.Circle sector perimeter formula: P = r(α + 2) ( α is in radians)Ellipse perimeter formula: P = π(3(a + b) – √((3a + b) * (a + 3b)))More items…•May 20, 2020

## What is length and width?

Definition: Length is the distance from one end to the other end of an object, while the width is the distance from side to side. Length is a type of measurement that shows how tall or long an object is.

## How do you find the length and width of a rectangle when given the perimeter?

To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. This number divided by 2 is the width.

## Is the length of a rectangle twice the width?

The length of a rectangle is twice the width. The number of square units in it’s area is four times the number of units in it’s perimeter.
