## NCERT Solutions for Class 6 Maths Chapter 10 Mensuration Ex 10.2

Question 1.
Find the areas of the following figures:

Solution :
(a)

 Cover Number estimate Area (i) Full-filled squares 9 9 squares (ii) Half-filed squares – – (iii) More than half-filed squares – – (iv) Less than half-filed squares – –

∴ Total area of the figure = 9 sq units

(b)

 Cover Number estimate Area (i) Full-filled squares 5 5 squares (ii) Half-filed squares – – (iii) More than half-filed squares – – (iv) Less than half-filed squares – –

∴ Total area of the figure = 9 sq units

(c) Full-filled squares = 2
Half-filled squares = 4
Area covered by full squares
= 2 × 1 sq unit = 2 sq units
Area covered by half squares = 4 × $$\frac{ 1 }{ 2 }$$ sq unit = 2 sq units
∴ Total area = 2 sq units + 2 sq units = 4 sq units.

(d) Full-filled squares = 8
Total area = Area covered by full squares = 8 × 1 sq unit = 8 sq units.

(e) Full-filled squares =10
∴ Total area = Area covered by full squares = 10 × 1 sq unit = 10 sq units.

(f) Full-filled squares = 2 Half-filled squares = 4 Area covered by full squares
= 2 × 1 sq unit = 2 sq units Area covered by half squares
= 4 × $$\frac{ 1 }{ 2 }$$ sq unit = 2 sq units
Total area = 2 sq units + 2 sq units = 4 sq units.

(g) Full-filled squares = 4 Half-filled squares = 4 Area covered by full squares
= 4 × 1 sq unit = 4 sq units Area covered by half squares
= 4 × $$\frac{ 1 }{ 2 }$$ sq unit = 2 sq units
∴ Total area = 4 sq units + 2 sq units.
= 6 sq units

(h) Full-filled squares = 5
∴ Total area = Area covered by full squares = 5 × 1 sq unit = 5 sq units.

(i) Full-filled squares = 9
∴ Total area = Area covered by full squares = 9 × 1 sq unit = 9 sq units.

(j) Full-filled squares = 2 Half-filled squares = 4 Area covered by full squares
= 2 × 1 sq unit = 2 sq units Area covered by half squares
= 4 × $$\frac{ 1 }{ 2 }$$ sq unit = 2 sq units
∴ Total area = 2 sq units + 2 sq units = 4 sq units.

(k) Full-filled squares = 4 Half-filled squares = 2 Area covered by full squares
= 4 × 1 sq unit = 4 sq units Area covered by half squares
= 2 × $$\frac{ 1 }{ 2 }$$ sq unit = 1 sq unit
∴ Total area = 4 sq units + 1 sq unit = 5 sq units.
(l)

 Cover Number estimate Area (i) Full-filled squares 4 4 × 1 sq unit = 4 sq units (ii) Half-filed squares 2 2 × $$\frac{ 1 }{ 2 }$$ sq unit = 1 sq unit (iii) More than half-filed squares 3 3 × 1 sq unit = 3 sq units (iv) Less than half-filed squares 4 –

(m)

 Cover Number estimate Area (i) Full-filled squares 9 9 × 1 sq unit = 9 sq units (ii) Half-filed squares 2 2 × $$\frac{ 1 }{ 2 }$$ = 1 sq unit (iii) More than half-filed squares 6 6 × 1 sq unit = 6 sq units (iv) Less than half-filed squares 4 –

∴ Total Area = 9 sq units + 1 sq. unit + 6 sq units = 16 sq units
(n)

 Cover Number estimate Area (i) Full-filled squares 11 11 × 1 sq unit = 11 sq units (ii) Half-filed squares 6 6 × $$\frac{ 1 }{ 2 }$$ = 3 sq unit (iii) More than half-filed squares 9 9 × 1 sq unit = 9 sq units (iv) Less than half-filed squares – –

∴ Total area = 11 sq units + 3 sq units + 9 sq units = 23 sq units.
