Q1. Count the squares and find out the area of the following diagrams:

11

Ans:

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

(b) The figure contains 5 fully filled squares only. Therefore, the area of this figure will be S 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 8 fully filled squares only. Therefore, the area of this figure will be 8 square units.

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

(f) The figure contains 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 only. Therefore, the area of this figure will be S square units.

(I) The figure contains 9 fully filled squares only. 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.

(l) From the given figure, it can be observed that,

Covered Area Number Area estimate ( sq units )
Fully filled squares 2 2
Half filled squares
More than half filled squares 6 6
Less than half filled squares 6 0

Total area = 6 + 2 = 8 sq units.

(m) From the above figure, it is observed that,

 

Covered Area Number Area estimate ( sq units )
Fully filled squares 5 5
Half filled squares
More than half filled squares 10 10
Less than half filled squares 9 0

Total area = 9 + 5 = 14 sq units

(n) From the above figure, it is observed that,

 

Covered Area Number Area estimate ( sq units )
Fully filled squares 8 8
Half filled squares
More than half filled squares 10 10
Less than half filled squares 9 0

Total area = 10 + 8 = 18 sq units.
