Answer 1

Answer:

81 900. 441. 256. 625

9. 30. 21. 16. 25

36. 120. 84. 64. 100

Step-by-step explanation:

when side=9m

area =side²=9²=81

perimeter=4*side=4*9=36

Now when area =900sqm

side=√area=√900=30

perimeter=4*side=4*30=120

Now perimeter=84

side=perimeter/4=84/4=21

area=side²=21²=441

Now side=16

area=side²=16²=256

perimeter=4*side=4*16=64

Now area=625

side=√area=√625=25

perimeter=4*side=4*25=100
