Mensuration, Exercise 10.2

Q.1. Find the areas of the following figures by counting square:

Ans:

(a) Number of filled square = 9

       Hence, Area covered by squares = 9 x1= 9 sq. units

(b) Number of filled squares = 5

       Hence, Area covered by filled squares = 5 x1= 5 sq. units

(c) Number of full filled squares = 2 and number of half-filled squares = 4

        Area covered by full filled squares = 2 x1 = 2 sq. units

And, Area covered by half-filled squares = 4x ½ = 2 sq. units

Hence, Total area = 2 + 2 = 4 sq. units

(d) Number of filled squares = 8

       Hence, Area covered by filled squares = 8 x 1 = 8 sq. units

(e) Number of filled squares = 10

       Hence, Area covered by filled squares = 10 x1= 10 sq. units

(f) Number of full filled squares = 2

       Number of half-filled squares = 4

       Area covered by full filled squares = 2 x1= 2 sq. units

And Area covered by half-filled squares = 4 x ½ = 2 sq. units

       Hence,  Total area = 2 + 2 = 4 sq. units

(g) Number of full filled squares = 4

       Number of half-filled squares = 4

        Area covered by full filled squares = 4 x 1 = 4 sq. units

And Area covered by half-filled squares = 4 x ½ = 2 sq. units

       Hence, Total area = 4 + 2 = 6 sq. units

(h) Number of filled squares = 5

       Hence, Area covered by filled squares = 5 x1= 5 sq. units

(i) Number of filled squares = 9

       Hence, Area covered by filled squares = 9 x1= 9 sq. units

(j) Number of full filled squares = 2

       Number of half-filled squares = 4

        Area covered by full filled squares = 2 x 1 = 2 sq. units

And Area covered by half-filled squares = 4 x ½ = 2 sq. units

       Hence, Total area = 2 + 2 = 4 sq. units

(k) Number of full filled squares = 4

       Number of half-filled squares = 2

Area covered by full filled squares = 4 x 1 = 4 sq. units

And Area covered by half-filled squares = 2 x ½  = 1sq. units

Hence, Total area = 4 + 1 = 5 sq. units

(l) Number of full filled squares = 3

Number of half-filled squares = 10

       Area covered by full filled squares = 3 x 1 = 3 sq. units

And Area covered by half-filled squares = 10 x ½ = 5 sq. units     

Hence, Total area = 3 + 5 = 8 sq. units

(m) Number of full filled squares = 7

Number of half-filled squares = 14

       Area covered by full filled squares = 7 x1 = 7 sq. units

And Area covered by half-filled squares = 14 x ½ = 7 sq. units

       Hence, Total area = 7 + 7 = 14 sq. units

(n) Number of full filled squares = 10

Number of half-filled squares = 16

        Area covered by full filled squares = 10 x 1 = 10 sq. units

And Area covered by half-filled squares = 16 x ½ = 8 sq. units

       Hence, Total area = 10 + 8 = 18 sq. units
