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

In the same way, if the perimeter and the width are known, the length can be calculated using the formula: Length(L) = P/2 – w. Where P = perimeter of the rectangle; and w = width of the rectangle.

What is the width if the perimeter is 90 cm and one length is 30 cm?

Answer: The width of the rectangle is 30 cm.

What is the formula of dimension of rectangle?

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.

What is the formula to find the perimeter of a rectangle?

To find the perimeter of rectangle we add the lengths of its sides. Thus, the perimeter of a rectangle with the length of a a and the width of b b is P = a + b + a + b = 2 × a + 2 × b = 2 × (a + b) P = a + b + a + b = 2 × a + 2 × b = 2 × (a + b)

What is the distance around a rectangle called?

The distance around a rectangle is called the perimeter of the rectangle. It is usually denoted by P P. To find the perimeter of rectangle we add the lengths of its sides. Thus, the perimeter of a rectangle with the length of a a and the width of b b is

What units are used to measure the area of a rectangle?

In other words, the area of a rectangle is the product of its length and width. The perimeter is measured in units such as centimeters, meters, kilometers, inches, feet, yards, and miles. The area is measured in units units such as square centimeters (cm2) (c m 2), square meters (m2) (m 2), square kilometers (km2) (k m 2) etc.

How to find the center of symmetry of a rectangle?

The center of symmetry is the point of intersection of its diagonals, O O. The distance around a rectangle is called the perimeter of the rectangle. It is usually denoted by P P . To find the perimeter of rectangle we add the lengths of its sides. Thus, the perimeter of a rectangle with the length of a a and the width of b b is
