Question

Find the area and Perimeter of the following figure, if area of small square is 1 sq cm.

Answer 1

In the given figure, there are 11 small squares.

Given, area of 1 small square = 1 sq cm

∴ Area of 11 small squares = 11 × Area of a small square  ...[∵ Area of square = Side × Side]

= 11 × 1 sq cm

= 11 sq cm

Also, side of a small square = 1 cm

Now, perimeter of the given figure = Sum of all its sides

= (1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1) cm

= 16 cm
