Perimeter of a Rectangle with Given Area Calculator

FAQs

What is the perimeter of a rectangle?

The perimeter is a quantity that measures the total length of 2-D or 3-D geometry's outer boundary: measurement starts from one point (say point z) and ends at the same point (point z). A rectangle is closed by four perpendicular sides, and two of them are unique. The perimeter of a rectangle equation is P=(a+b+a+b), which is basically a measure of all sides. In a simplified form: P=2×(a+b).

How do you find the perimeter of a rectangle given area?

You can use the following points to find the perimeter of a rectangle given area: You need to know at least one side of the rectangle: call it Side 1; Now use the area equation, i.e., A=Side 1 × Side 2 to find the unknown side Side 2; and Finally, use Side 1 and Side 2 to find the perimeter, i.e., P=2×(a+b). Awesome! Now you know how to find the perimeter of a rectangle. Use our perimeter of a rectangle with given area calculator to get the perimeter at supersonic speed!

How can you calculate the perimeter of a rectangle whose area is 20 m^2 and length is 4 m?

To find the perimeter: Find the width w by diving the area A=20 cm^2^ by length l =4 cm, i.e., w=20/4=5; and Once you get the width (w), the perimeter is calculated as P=2×(w+l)=2×(5+4)=20 m.

What is the difference between the area and perimeter of a rectangle?

The difference between area and perimeter are as follows: The area is a quantity that shows how much space a geometry occupies, whereas the perimeter gives us the measurement of the total length of the outer boundary of the geometry; The area of a rectangle equation is A=length×width, and the perimeter of a rectangle equation is P=2×(length+width). SI unit of area is m2, and for perimeter, it is m.

What is the perimeter of a rectangle 11m x 5m?

The perimeter of this rectangle is 32 m. 11 m and 5 m are the length and width of a rectangle, respectively. Knowing length and width, you can calculate perimeter as P=2×(11+5)=32.
