Question

a circular wire of radius 21 m cut and bent into form a square then find the area of square

Answer 1

Hey Friend,
__________________________________

Thanks for Question !

Solution ➡ As we know that perimter of Circke will be same of perimter of square in this question.

Circumference = 2 × 22/7 × 21cm
= 2 × 22 × 3 cm
= 132 cm

Now perimter = 4 × side

132 cm = 4 × side
132 cm /4 = side
33 cm = side

Area of square = side^2
= (33 cm)^2
= 1089 cm^2

Hope it helps☺!

Answer 2

Circumference of circle= 2πr
                      =2 x 22/7 x 21
                      =132m

Perimeter of square = 132m
                            4a = 132m
                              a = 33m
Area of square = a^2
                         =1089sq m
