Question

a person walks at the rate of 4km hour how long will he take to go round a square park 5times whose area is 2500 m square

​

Answer 1

⭕ YᎾUℛ ᎯℕЅᏇℰℛ ⭕

Area of square park = a² = 2500m

side of square park =

$\sqrt{2500} = 50m$

Perimeter of park = 4 x 50 = 200m

5 times of park = 200 x 5 = 1000m

1000m = 1km

speed of man = 4 km / hr

time taken by man =

1km / 4km pr hr = 0.25hr

0.25 hr = 15 min
