• 11.2 Area of a parallelogram & triangle
• 11.3 Circles : Circumference & Area
• 11.4 Perimeter of Polygons
• 11.5 Conversion of units and its applications ## Some important Facts about Perimeter and Areaworksheet for class 7

1. Perimeter is the distance around a closed figure whereas area is the part of plane occupied by the closed figure.
2. We have learnt how to find perimeter and area of a square and rectangle in the earlier class. They are: (a) Perimeter of a square = 4 × side (b) Perimeter of a rectangle = 2 × (length + breadth) (c) Area of a square = side × side (d) Area of a rectangle = length × breadth
3. Area of a parallelogram = base × height

## SQUARES AND RECTANGLES

Ayush and Deeksha made pictures. Ayush made his picture on a rectangular sheet of length 60 cm and breadth 20 cm while Deeksha made hers on a rectangular sheet of length 40 cm and breadth 35 cm. Both these pictures have to be separately framed and laminated. Who has to pay more for framing, if the cost of framing is  3.00 per cm? If the cost of lamination is  2.00 per cm2 , who has to pay more for lamination?

For finding the cost of framing, we need to find perimeter and then multiply it by the rate for framing. For finding the cost of lamination, we need to find area and then multiply it by the rate for lamination
