## What is the perimeter in inches of a rectangle?

We know that the perimeter of a rectangle is equal to twice the sum of its length and width. Hence, Perimeter of a rectangle = 2(l+w). Applying the values of length and width in this formula, we have Perimeter = 2(l + w) = 2(120 + 85)= 2 × 205 = 410 inches.

### How do you find the perimeter of a rectangle inside?

To find the perimeter of a rectangle, add the lengths of the rectangle’s four sides. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width). Multiply both the height and width by two and add the results.

#### What is a formula of perimeter of rectangle?

The perimeter of a rectangle is the total length of all the sides of the rectangle. Perimeter of the given rectangle is a + b + a + b. Since opposite sides of a rectangle are always equal, we need to find the dimensions of only two sides to find the perimeter of a rectangle.

What is a perimeter in math?

The perimeter of a shape is the total measurement of all the edges of a shape e.g. a triangle has three edges, so its perimeter is the total of those three edges added together. The perimeter of a rectangle can be calculated by adding the length and width together and doubling it.

How is perimeter written?

The formula for the perimeter of a rectangle is often written as P = 2l + 2w, where l is the length of the rectangle and w is the width of the rectangle. The area of a two-dimensional figure describes the amount of surface the shape covers.

## How do you find area and perimeter?

Divide the perimeter by 4: that gives you the length of one side. Then square that length: that gives you the area. In this example, 14 ÷ 4 = 3.5.

### How do I find the perimeter and area of a rectangle?

The perimeter P of a rectangle is given by the formula, P=2l+2w , where l is the length and w is the width of the rectangle. The area A of a rectangle is given by the formula, A=lw , where l is the length and w is the width.

#### How do you calculate the dimensions of a rectangle?

Method 1 of 3: Using the Length and the Width Set up the formula for the Pythagorean Theorem. You use the Pythagorean Theorem because a diagonal of a rectangle cuts the rectangle into two congruent right triangles. Plug the length and the width into the formula. These should be given, or you should be able to measure them. Square the length and width, then add these numbers together.

What is the minimum area of a rectangle?

The area of a rectangle is calculated as the product of base width and height. In the given case, these values are 6 km and 11 km; or 11 km and 6 km. In either case, the area of rectangle will be 11 km x 6 km = 66 square km. There is no minimum or maximum area, both are the same; 66 square km.

What is the formula for finding the perimeter?

The perimeter is the sum of all sides of a figure to get one length. So, to find the perimeter, the formula is base + height + base + height. If the base is 10 inches and the height is 5 inches, you would have: Perimeter: 10 + 5 + 10 + 5 = 30 inches.

## How do you find the missing side of a rectangle?

Divide the total area by the side measurement you know. This will allow you to find the measurement of the missing side of your rectangle, whether it is the length or the width. Finding this missing piece of information will then allow you to calculate perimeter.
