Mensuration Class 6 Exercise 10.2 Solutions – 6th Class Maths 10.2 Exercise Solutions
Question 1.
Find the areas of the following figures by counting square :
Solution:
a) Number of full squares = 9
Area of 1 square = 1 sq. unit.
∴ Area of 9 squares = 9 × 1 sq. unit = 9 sq. units.
b) Area of the figure = 5 sq. units
c) Number of full squares = 2
Number of half squares = 4
∴ Area of the figure = 2 + 4 × \(\frac { 1 }{ 2 }\) = 2 + 2 = 4sq. units.
d) Area of the figure = 8 sq. units
e) Area of the figure = 10 sq.units
f) Number of full squares = 2
Number of half squares = 4
∴ Area of the figure = 2 + 4 × \(\frac { 1 }{ 2 }\) = 2 + 2 = 4 sq. units.
g) Number of full squares = 4
Number of half squares = 4
∴ Area of the figure = 4 + 4 × \(\frac { 1 }{ 2 }\) = 4 + 2 = 6 sq. units.
h) Area of the figure = 5 sq.units
i) Area of the figure = 9 sq. units
j) Number of full squares = 2
Number of half square = 4
∴ Area of the figure = 2 + 4 × \(\frac { 1 }{ 2 }\) = 2 + 2 = 4 sq. units.
k) Number of full squares = 4
Number of half squares = 2
∴ Area of the figure = 4 + 2 × \(\frac { 1 }{ 2 }\) = 4 + 1 = 5 sq. units.
l) Number of full squares = 4
Number of squares more than half = 3
Number of half squares = 2
∴ Area of the figure = 4 + 3 + 2× \(\frac { 1 }{ 2 }\) = 4 + 3 + 1 = 8 sq. units.
m) Number of full squares = 6
Number of more than half squares = 8
∴ Area of the figure = 6 + 8 = 14 sq. units.
n) Number of squares = 9
Number of more than half squares = 9
∴ Area of the figure = 9 + 9 = 18 sq. units.
