Answer 2

Step-by-step explanation:

2) Given that:-

) Given that:-Perimeter of a square=40m

) Given that:-Perimeter of a square=40m=>4×length of the side =40m

) Given that:-Perimeter of a square=40m=>4×length of the side =40m=>length of the side=40/4

) Given that:-Perimeter of a square=40m=>4×length of the side =40m=>length of the side=40/4=>Side of the square =10m

Area of the square =side×side

=> A=10×10

=>A=100 m²

3)

Circumference of a circle =44cm

=>2πr=44

=>πr=44/2

= πr=22

=>(22/7)r=22

=>r=22×(7/22)

=>r=7cm

Radius =7cm
