How do you find the perimeter if you have the dimensions?

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. Fill in the perimeter equation.

How do you find a rectangles perimeter?

The perimeter of a rectangle is the total length of all the sides of the rectangle. Hence, we can find the perimeter by adding all four sides of a rectangle. Perimeter of the given rectangle is a + b + a + b.

What is the formula of dimension of rectangle?

To calculate the length and width of a rectangle first, calculate the value of width ‘w’ by using the area of rectangle formula that is, ‘w = A/l’.

How do you find the length and width if you know 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.

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.

How do you calculate the area of a rectangle?

To calculate the area of a rectangle, multiply the adjacent sides together. Be careful not to multiply the opposite sides together. The formula to calculate the area is A = ab, where a and b are the adjacent sides of the rectangle.

How do you determine perimeter?

Perimeter simply measures the distance around an area. It can be measured in inches, feet, yards, miles, centimeters, meters, kilometers, and so on (any standard distance measurement). You can measure the perimeter of nearly any shape, you just add together the measure of each of its sides.
