Question

A rectangular field is 92 m by 78 m. Ajay walks around it at the rate of 3 km per hour. What time will he take in taking 2 rounds? ​

Answer 1

Step-by-step explanation:

perimeter of a rectangle is 2(L +B)

perimeter of the rectangle =2(92+78)

perimeter of the rectangle =2(170)=340meters

per around distance =340m=0.34km

speed =3km/hr

speed =distance /time

time =distance /speed

time =0.34km/(3km/hr)

time =0.113 hr

2 rounds =0.226hr
