How to Calculate Area and Perimeter of a Rectangle

What is the formula to calculate the area of a rectangle?

A. length x width

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

B. 2 x (length + width)

Answer:

To calculate the area of a rectangle, you can use the formula:

Area = length x width

And to calculate the perimeter of a rectangle, you can use the formula:

Perimeter = 2 x (length + width)

A rectangle is a geometric shape with four sides where opposite sides are equal in length. The area of a rectangle is the total space enclosed by the rectangle, while the perimeter is the distance around the outside of the rectangle.

Let's say you have a rectangle with a length of 5 units and a width of 3 units. To find the area, simply multiply the length by the width: Area = 5 x 3 = 15 square units. To find the perimeter, use the formula: Perimeter = 2 x (5 + 3) = 2 x 8 = 16 units.

Remember, when calculating the area and perimeter of a rectangle, always make sure to use the correct measurements for the length and width, and apply the formulas correctly to get the accurate results.
