## Chapter 10 Mensuration Exercise 10.2

Question 1: Find the areas of the following figures by counting square: a) The figure contains only 9 fully filled squares. Therefore, the area of this figure will be 9 square units.

b) The figure contains only 5 fully filled squares. Therefore, the area of this figure will be 5 square units.

c) The figure contains 2 fully filled squares and 4 half-filled squares. Therefore, the area of this figure will be 4 square units.

d) The figure contains only 8 fully filled squares. Therefore, the area of this figure will be 8 square units.

e) The figure contains only 10 fully filled squares. Therefore, the area of this figure will be 10 square units.

f) The figure contains only 2 fully filled squares and 4 half-filled squares. Therefore, the area of this figure will be 4 square units.

g) The figure contains 4 fully filled squares and 4 half-filled squares. Therefore, the area of this figure will be 6 square units.

h) The figure contains 5 fully filled squares. Therefore, the area of this figure will be 5 square units.

i) The figure contains 9 fully filled squares. Therefore, the area of this figure will be 9 square units.

j) The figure contains 2 fully filled squares and 4 half-filled squares. Therefore, the area of this figure will be 4 square units.

k) The figure contains 4 fully filled squares and 2 half-filled squares. Therefore, the area of this figure will be 5 square units.
