Step-by-step explanation:

a) Area of square = (side)^2

49cm^2. = (side)^2

√49 = side

7 cm. = side

Perimeter of square = 4× side

= 4× 7

= 28 cm

b) Area of square = (side)^2

100cm^2. = (side)^2

√100. = side

10cm. = side

Perimeter of square = 4× side

= 4× 10

= 40cm

c) Area of square = (side)^2

2.56m^2. = (side)^2

√2.56. = side

1.6cm. = side

Perimeter of square = 4× side

= 4× 1.6

= 6.4cm

hope it is helpful ...
