Question

Reena runs along the sides of the square garden which is 85 m long . if she covers 50 cm in a one step, how many steps will she take run once round the garden ?​

Answer 1

Side of square= 85m

Perimeter= 4×side=4×85m=340m

Now

Use unitary method..

0.5m(50cm)= 1 step

340m=1/0.5×340 steps= 680 steps

Thank You!!!!

Answer 2

First we will convert 85 m to cm it will be 8500 now in the statement we will write

The side of square garden = 8500 cm

4 × side

4×8500

34000

34000/50= 680

Therefore she takes 680 steps to complete one round of the garden
