Perimeter of a Rectangle Formula = 2 (Length + Width) Types of RectanglesĪ quadrilateral whose opposite sides are equal and adjacent sides meets at 90° is called a rectangle. The formula for the perimeter, 'P' of a rectangle whose length and (breadth) width are 'l' and 'w' respectively is 2(l + w). The formula used to calculate the perimeter of a rectangle is explained below. For example, if you need to decorate the border of your rectangular notebook, you can easily calculate how much ribbon you would need by finding the perimeter or if you need to put a fence around your garden, the perimeter of the garden will give you the exact length of wire you would need. It can be taken as the sum of the total measure of the length and width of the rectangle and it is expressed in linear units like cm, inches, and so on. The perimeter of a rectangle is the length of the total boundary of a rectangle. The formula for the area of a rectangle whose length and breadth (width) are 'l' and 'w' respectively is the product of its length and width, that is: Thus, the area of a rectangle can be calculated when its sides (length and width) are known. Thus, the Area of the rectangle = 12 square inches. Since the unit of this rectangle is given in inches, the area is measured and written in square inches. We have already learned that area is measured in square units. How many squares can you observe? There are 12 squares in all. Now, count the number of unit squares in the below figure. Each unit square is a square of length 1 inch. Let us draw unit squares inside the rectangle. For example, let us consider a rectangle of length 4 inches and width 3 inches. We can use the formula of the area of a rectangle to find the space occupied by these objects. Some examples of rectangular shapes are the flat surfaces of laptop monitors, blackboards, painting canvas, etc. In other words, the space occupied by a rectangle is the area of the rectangle. The area of a rectangle is the number of unit squares that can fit into a rectangle. Similarly, if we know the perimeter and length of a rectangle, we can find the breadth using the perimeter formula by substituting the values or we can reframe the perimeter formula as, Breadth = (Perimeter ÷ 2) - Length Breadth of rectangle formula: If we know the area and length of a rectangle, we can find the breadth using the area formula by substituting the values or we can reframe the area formula as, Breadth = Area of rectangle ÷ Length.Similarly, if we know the perimeter and breadth of a rectangle, we can find the length using the perimeter formula by substituting the values or we can reframe the perimeter formula as, Length = (Perimeter ÷ 2) - Breadth Length of rectangle formula: If we know the area and breadth of a rectangle, we can find the length using the area formula by substituting the values or we can reframe the area formula as, Length = Area of rectangle ÷ Breadth.Perimeter of rectangle formula: If we know the length and breadth of a rectangle, we can find the perimeter using the formula, Perimeter of rectangle = 2 (Length + Breadth).Area of rectangle formula: If we know the length and breadth of a rectangle, we can find the area using the formula, Area of rectangle = Length × Breadth.A few rectangle formulas are given below: All rectangles are parallelograms but all parallelograms are not rectangles.Ī rectangle has a few basic formulas which can be noted in order to find the missing or unknown values.
Multiply the cm 2 value by 0.0001 to get mm 2 Multiply the m 2 value by 10 000 to get cm 2 Multiply the m 2 value by 1000000 to get mm 2
