Answer 2

Answer:

I) let the side be 's'

area=s^2=400cm^2

so, s=✓400cm^2=20 cm

therefore, perimeter=4s=4x20cm=80cm

ii) let the side be 's'

area=s^2=225m^2

so, s=✓225m^2= 15m

therefore, perimeter=4s=4x15m=60m

iii) let the side be 's'

area=s^2=289m^2

so,s=✓289m^2=17m

therefore, perimeter=4s=4x17m=68m

iv) let the side be 's'

area=s^2=5.76m^2

so,s=✓5.76m^2=2.4m

therefore, perimeter=4s=4x2.4m=9.6m
