Perimeter of a rectangle=AB+BC+CD+DA = l+b+l+b
EXAMPLE 1. The length and breadth of a rectangle is equal to 12cm and 8cm.Find its Perimeter of rectangle= Perimeter. 2*(l+b) = 2*(12cm+8cm)
AREA OF RECTANGLE The area of rectangle ABCD is equal to the Multiplication of its Length and Breadth.. Area of Rectangle=Length*Breadt h
EXAMPLE 1.Find the Area of a Rectangle whose Length & Breadth are as underLength = 6m , Breadth = Area of Rectangle=l*b 3.5m. =6m* 3.5m =21.0m2 = 21m2
POINTS TO REMEMBER The diagonals of a rectangle are equal and bisect each other. A rect angle wit h four equal sides is a s quare.
