State whether the statement are True or False.In Fig,(a) area of (i)

1.	State whether the statement are True or False.In Fig,(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 13 unit squares.(d) Perimeter of (ii) is 18 units.
Answer» (a) area of (i) is the same as the area of (ii). True. By observing the figure, we can say that area of booth figure same, because number of blocks used in both figures are same. (b) Perimeter of (ii) is the same as (i). False. By observing the figure, we can say that there are 2 new sides are added in figure (ii). Therefore, the perimeter of (ii) is not same as (i). (c) If (ii) is divided into squares of unit length, then its area is 13 unit squares. False. We know that, area of square = side × side Then area of 1 square = 1 × 1 = 1 unit squares There are 12 squares in figure (ii). Therefore, area of figure (ii) = 12 × 1 = 12 unit squares (d) Perimeter of (ii) is 18 units. True. The perimeter refers to the total length of the sides or edges of a polygon.

Answer»

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

True.

By observing the figure, we can say that area of booth figure same, because number of blocks used in both figures are same.

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

False.

By observing the figure, we can say that there are 2 new sides are added in figure (ii).

Therefore, the perimeter of (ii) is not same as (i).

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

False.

We know that, area of square = side × side

Then area of 1 square = 1 × 1

= 1 unit squares

There are 12 squares in figure (ii).

Therefore, area of figure (ii) = 12 × 1 = 12 unit squares

(d) Perimeter of (ii) is 18 units.

True.

The perimeter refers to the total length of the sides or edges of a polygon.
