The formula for finding the breadth (b) of a rectangle is b = Area / Length. Where Length (l) is the longer side of the rectangle, and Area (A) is the product of the length and breadth.

Note: The breadth and width of a rectangle are used interchangeably, and they refer to the same dimension.

Length and Breadth of Rectangle

Let us Understand the Formula through Examples

Example 1: A rectangle has an area of 120 square meters and a length of 20 meters. What is the breadth of the rectangle?

Solution: Breadth = 120 ÷ 20 = 6 meters

Example 2: A rectangle has an area of 144 square inches and a length of 12 inches. What is the breadth of the rectangle?

Solution: Breadth = 144 ÷ 12 = 12 inches

Example 3: A rectangle has an area of 150 square centimeters and a length of 30 centimeters. What is the breadth of the rectangle?

Solution: Breadth = 150 ÷ 30 = 5 centimeters

Important Points to Remember while Finding Breadth of a Rectangle

  • The breadth of a rectangle is one of the four important measurements required to fully describe the size and shape of a rectangle.
  • The breadth of a rectangle is equal to the width of the rectangle if it is oriented with its sides parallel to the x- and y-axes.
  • The breadth and length of a rectangle can be interchanged to create a different rectangle with the same area.
  • In a square, the breadth and length are equal, which makes finding the breadth of a square easier than a rectangle.
