Find the area and perimeter of the following figure, if area of small square is 1 sq cm.
उत्तर
In the given figure, there are 13 small squares
Given, area of 1 small square = 1 sq cm
∴ Area of 13 small squares = 13 × Area of a small square
= 13 × 1 sq cm
= 13 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 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 ) cm
