Formula for Calculating Lateral Surface Area of a Rectangle

In mathematics, there are several formulas used to calculate the surface area and volume of various shapes. One such formula is used to find the lateral surface area of a rectangle. In this article, we will explore what is the formula for calculating the lateral surface area of a rectangle.

A rectangle is a two-dimensional shape with four sides and four right angles. The lateral surface area of a rectangle refers to the sum of the areas of its four sides. To find the lateral surface area of a rectangle, you need to know its length (L), breadth (B) and height (H).

The formula for calculating the lateral surface area of a rectangle is:

TSA = 2(l × h) + 2(b × h)

Where TSA stands for Total Surface Area.

To understand this formula better, let's break it down. The first part of the formula, '2(l × h)', calculates the area of two opposite sides of the rectangle. These two sides have a length equal to L and a height equal to H. Similarly, the second part of the formula, '2(b × h)', calculates the area of the other two opposite sides.

When you add these two parts together, you get the total lateral surface area of the rectangle. This formula is simple to use and can be applied to any rectangular shape.

In conclusion, the formula for calculating the lateral surface area of a rectangle is TSA = 2(l × h) + 2(b × h). By using this formula, you can easily find the lateral surface area of any rectangular shape.
