The Ratio Between The Length And The Breadth Of A Rectangular Park Is 3:23:2. If A Man Cycling Along The Boundary Of The Park At The Speed Of 1212 Km/hr Completes One Round In 88minutes, Then What Is The Area Of The Park (in Sq. M)? |

Answer» Let LENGTH =3xkm, breadth =2xkm Distance travelled by the man at the speed of 1212 km/hr in 88 minutes =2(3x+2x)=10x Therefore, 12×8/60=10x x=4/25 km=160 m Area =3x×2x=6x2 =6×1602=153600 m2. Let length =3xkm, breadth =2xkm Distance travelled by the man at the speed of 1212 km/hr in 88 minutes =2(3x+2x)=10x Therefore, 12×8/60=10x x=4/25 km=160 m Area =3x×2x=6x2 =6×1602=153600 m2. |
