Question

A rectangular park is 100 m long and 50 m wide. How many rounds are needed to cover the distance of 1.2 km?​

Answer 1

Answer:

4 rounds

Step-by-step explanation:

Circumference of rectangular park = 2(l+b)

= 2(100+50)

= 2×150=300

(1.2km=1200m)

Number of rounds = distance/circumference

= 1200/300

= 4

Answer 2

Here the length and breadth of a rectangular park is given

length = 100 m

breadth = 50 m

first, we will find the perimeter of the park

perimeter = 2 ( length + breadth )

                = 2 ( 100 + 50 )

                 = 300 m

300 m = 300 / 1000 km

           = 0.3 km

So, in one round a distance of 0.3 km will be covered

So, rounds needed to cover a distance of 1.2 km= 1.2 / 0.3

                                                                                 = 4

Hence, 4 rounds will be needed to cover a distance of 1.2 km
