Q58 of 131 Page 226

State whether the statements are True or False.

In Fig. 9.27,


A. area of (i) is the same as the area of (ii).



B. Perimeter of (ii) is the same as (i).


C. If (ii) is divided into squares of unit length, then its area is 13unit squares.


D. Perimeter of (ii) is 18 units.

(a) True
Area of both figures is same, because in both number of blocks are same.


(b) False
Because 2 new sides are added in (ii). So, the perimeter of (ii) is greater than (i).


(c) False


∴ Area of 1 square = 1 × 1


= 1 unit squares


∵ Number of squares = 12


So, total area = 12 × 1 = 12 unit squares


(d) True


∵ Perimeter is the sum of all sides. So, it is 18 units.
