sonali is running around a garden of length 48mbreadth 31m find the distance covered by her in 3 rounds

Answer :

Given  :  Garden of length 48 m breadth 31 m

We know perimeter of rectangle  =  2 ( Length + Breadth )

So,

Distance covered by Sonali in one round  =  2 ( 48 + 31 ) =  2 ×79  = 158 m

Therefore, 

Distance covered by Sonali in three round  = 3 × 158 = 474 m                                              ( Ans )

48+31 = 79 * 3 = 237m

PERIMETER  =  2( l   +  b )
                         =  2(  48  +  31 )m
                          =2  *  79 m
                         =158 m
Distance covered in 3 rounds  =  3  *  158 m
                                                 =  474  m
