Question

gaurav makes 7 round of a park having length and breadth as 500m and 200m respectively how much distance gaurav has travelled give answer in km.

Answer 1

no. of rounds taken=7

perimeter of rectangle=2(l+b)

length=500m

breadth= 200m

So, 7*2(200m+500m)

=7*(400m+1000m)

7*(1400m)

=9800m

Answer 2

Given :-
length of the park = 500m
breadth of the park = 200m
so,
perimeter of the park = 2×(length+breadth)
= 2 ×(500+200)
= 2 × 700 = 1400 m = 1.4 km

7 round of park = 7×1.4 = 9.8 km answer
