![]() ![]() A perimeter is the length of the boundary of any geometric figure.The perimeter of a rectangle is given by the formula, P = 2, where l is the length and b is the breadth of the rectangle.Concrete border for a house construction plan, which is feasible using the perimeter formula.The length of swimming races is determined by the perimeter when constructing a rectangular swimming pool.It can be used for a variety of art and craft projects, such as adding colorful ribbons or ropes to the edge of rectangular cardboard.The perimeter formula can be used to calculate the length of a rectangular field or garden for fencing purposes.The perimeter of a rectangle has several real-life practical applications. Hint: Using P= 2(l+w), find the breadth and substitute in the area formula. The perimeter of a rectangular plot of land is 100 m. Hint: Using A= l x w, find the length and then substitute in the perimeter formula. The area of a children’s park is 900 m 2. Solution: Area of the rectangular sheet, A= 500 cm 2 Determine the perimeter of the rectangular sheet. Width of the rectangular plot = 12 m Type 3: Finding Perimeter When Area and Length of One Side is KnownĮxample: A rectangular sheet of paper has an area of 500 cm 2 and the length of one of its sides is 20 cm. Determine the width of the rectangular plot, if the length of the garden is 16 m. TYPE 2: Finding the Unknown Side When One Side and Perimeter are KnownĮxample: The perimeter of a rectangular garden is 56 m. Thus, the perimeter of the rectangle is 40 cm. Using the perimeter of the rectangle formula, Important Questions on Finding Perimeter of Rectangle TYPE 1: Finding Perimeter When Length and Width are KnownĮxample: Calculate the perimeter of a rectangle with sides of length 12 cm and breadth 8 cm. Relation Between Area and Perimeter of Rectangle STEP 5: The value calculated after substitution is the perimeter of the given rectangle.STEP 4: Substitute the known values of length and breadth of the rectangle in the formula.STEP 3: Write down the perimeter of the rectangle formula.STEP 2: Convert all the linear measurements given into the same units.STEP 1: Identify the length and breadth or width of the rectangle given in the question. ![]() The perimeter of the rectangle can be obtained in three simple steps as follows: The perimeter of a rectangle = 2( sum of the adjacent sides of the rectangle) Taking the common factor out, the equation can be reduced to, We know that in a rectangle the opposite sides are equal and parallel. Let the length of the rectangle be l and the breadth or width be w Let us deduce the perimeter of a rectangle formula. The perimeter of a rectangle is the total length around its boundary. The width of the given rectangle is 15 cm.The perimeter of a Rectangle formula is mathematically given as:Īs the opposite sides of a rectangle are parallel and equal, its perimeter is equal to twice the width plus twice the length of the rectangle, and it is denoted by the letter "P". Using the formula P = 2 ( l + w), we can say that 2 (35 + w) = 100 The perimeter of a rectangle is 100 cm.The perimeter of the given rectangle is 80 m. Since the length of the yard is 25 m, the width of this rectangular yard is 25 m – 10 m or 15 m. The length of the rectangular yard is 10 m more than the width. If the yard’s length is 25 m, find the perimeter of this rectangular yard? The length of a rectangular yard is 10 m more than the width. ![]() The perimeter of the given rectangle is 58 cm. ![]() Perimeter of the rectangle, P = 2 ( l + w) = 2 (25 + 4) = 58 The length of a rectangle is 25 cm and the width is 4 cm.Solved Examples On Perimeter of Rectangle To draw a border with limestone around a rectangular ground and determine how much limestone would be required to mark the ground’s total periphery.To measure the length of barbed wire required to create a fence around a rectangular plot of land.To find out the distance covered by walking around a rectangular park. ![]()
