Class –VI Mathematics

(Ex. 10.2)

Question 1.Find the areas of the following figures by counting squares:

Answer:

(a) Number of filled square = 9

{tex}\therefore {/tex} Area covered by squares = 9 x 1 = 9 sq. units

(b) Number of filled squares = 5

{tex}\therefore {/tex} Area covered by filled squares = 5 x 1 = 5 sq. units

(c) Number of full filled squares = 2

Number of half filled squares = 4

{tex}\therefore {/tex} Area covered by full filled squares = 2 x 1 = 2 sq. units

And Area covered by half filled squares = x = 2 sq. units

{tex}\therefore {/tex} Total area = 2 + 2 = 4 sq. units

(d) Number of filled squares = 8

{tex}\therefore {/tex} Area covered by filled squares = 8 x 1 = 8 sq. units

(e) Number of filled squares = 10

{tex}\therefore {/tex} Area covered by filled squares = 10 x 1 = 10 sq. units

(f) Number of full filled squares = 2

Number of half filled squares = 4

{tex}\therefore {/tex} Area covered by full filled squares = 2 x 1 = 2 sq. units

And Area covered by half filled squares = x = 2 sq. units

{tex}\therefore {/tex} Total area = 2 + 2 = 4 sq. units

(g)Number of full filled squares = 4

Number of half filled squares = 4

{tex}\therefore {/tex} Area covered by full filled squares = 4 x 1 = 4 sq. units

And Area covered by half filled squares = x = 2 sq. units

{tex}\therefore {/tex} Total area = 4 + 2 = 6 sq. units

(h)Number of filled squares = 5

{tex}\therefore {/tex} Area covered by filled squares = 5 x 1 = 5 sq. units

(i)Number of filled squares = 9

{tex}\therefore {/tex} Area covered by filled squares = 9 x 1 = 9 sq. units

(j)Number of full filled squares = 2

Number of half filled squares = 4

{tex}\therefore {/tex} Area covered by full filled squares = 2 x 1 = 2 sq. units

And Area covered by half filled squares = x = 2 sq. units

{tex}\therefore {/tex} Total area = 2 + 2 = 4 sq. units

(k)Number of full filled squares = 4

Number of half filled squares = 2

{tex}\therefore {/tex} Area covered by full filled squares = 4 x 1 = 4 sq. units

And Area covered by half filled squares = x = 1 sq. units

{tex}\therefore {/tex} Total area = 4 + 1 = 5 sq. units

(l)Number of full filled squares = 3

Number of half filled squares = 10

{tex}\therefore {/tex} Area covered by full filled squares = 3 x 1 = 3 sq. units

And Area covered by half filled squares = x = 5 sq. units

{tex}\therefore {/tex} Total area = 3 + 5 = 8 sq. units

(m)Number of full filled squares = 7

Number of half filled squares = 14

{tex}\therefore {/tex} Area covered by full filled squares = 7 x 1 = 7 sq. units

And Area covered by half filled squares = x = 7 sq. units

{tex}\therefore {/tex} Total area = 7 + 7 = 14 sq. units

(n)Number of full filled squares = 10

Number of half filled squares = 16

{tex}\therefore {/tex} Area covered by full filled squares = 10 x 1 = 10 sq. units

And Area covered by half filled squares = x = 8 sq. units

{tex}\therefore {/tex} Total area = 10 + 8 = 18 sq. units
