Answer:
Preeti cover the park 3 times
Nidhi covers the park 4 times
dimensions of park of Nidhi = (park b) = side = 550m
dimensions of park of Preeti :- (Park a)
L = 350m
B = 250m
perimetre of park a = 2(l+b)
= 2(350 + 250)
=2 × 600m
=1200m = 1200 ÷ 1000 = 1.2km
1.2km × 3 = 3.6km was ran by preeti
perimetre of park b = s × 4
= 550m × 4
= 2200m = 2200 ÷ 1000 = 2.2km
= 2.2 × 4 = 8.8km
so, 8.8km - 3.6km = 5.2km
therefore, Preeti covers less distance by Nidhi by 5.2km / 5200m
