(b) 100 cm²
(c)2.56m²​

Answer 1

Answer:

My ans is

a) 7

b) 10

c) 1.28

Answer 2

Step-by-step explanation:

a . suppose , side of this square is a cm

a² = 49

a = 7

perimeter of this square is 4*7 cm

= 28 cm

b . suppose , side of this square is b cm

b² = 100

b = 10

perimeter of this square is 4*10 cm

= 40 cm

c . suppose , side of this square is c cm

c² = 2.56

c = 1.6

perimeter of this square is 4*1.6 cm

= 6.4 cm

perimeter of a square is 4a (here 'a' is side of the square)

area of a square is a²(here 'a' is side of the square)
