A leveller with a `1.5` meters long metallic strip is used to level an area of 45 square metres Then calculate the length of the field which is levelled

Text Solution

Verified by Experts

Area of the field plough, `(A)=45m^(2)` the length of the metal of the metal strip =1.5 m
`:.` Area of the field ploughed =length of field ploughed `xx` length of metal strip.
`:. 45m^(2)=lxx1.5m`
`l=(45m^(2))/(1.5m)=30m`
