Answer 1

Solution:-
a. Perimeter= 4×side
= 4×25
= 100cm.
b.Perimeter= 2(l+b)
=2(40+10)
= 80+20
= 100cm
c.Perimeter= 2(l+b)
= 2(30+20)
= 60+40
=100cm.

Answer 2

heya....

Here is your answer....

1) Perimeter of square = 4a

= 4×25

= 100

2) perimeter of rectangle = 2 (a+b)

= 2 (30+20)

= 2(50)

= 100

3) Perimeter of rectangle = 2 (a +b)

= 2 (10+40)

= 2 (50)

= 100

4) perimeter of triangle = a+b+c

= 30+40+30

= 100
