Question

A rectangular field is 50 m by 40 m. Mhesh goes tem times round it .how much distance does he cover

Answer 1

Solution :

Dimensions of a rectangular field :

Length ( l ) = 50 m

breadth ( b ) = 40 m

Distance covered in one round

= perimeter of the field

= 2( l + b )

Now ,

distance covered in 10 rounds

= 10 × [ 2( l + b ) ]

= 20 ( 50 + 40 )

= 20 × 90

= 1800 m
