Find the area and Perimeter of each of the following figures, if area of each small square is 1sqcm.

(i) There are 11 small squares


Area of 11 squares = 11 × 1


= 11 sq.cm



Perimeter = 1 + 1 +1 +1 +1 +1 +1 +1 +1 +1 +1 +1 +1 +1 +1 +1


= 16 cm


(ii) In the given figure there are 13 small squares


Area of 13 squares = 13 × 1


= 13 sq.cm



Perimeter = 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


= 27 cm


(iii) In the given figure there are 13 small squares


Area of 13 squares = 13 × 1


= 13 sq.cm



Perimeter = 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 + 1
