Question

how many hectares are there in a rectangular field of length 250 m and breadth 140 m​

Answer 1

Length, l = 250 m

Breadth, b = 140 m

Hence, Area = l*b = 250*140 = 35000 m^2 = 3.5 hectares

Hence, There are 3.5 hectares.

Answer 2

Given lenght =250m

Given Breadth =140m

Area in rectangular field=(l*b)

Area = (250*140)=35000m^2

Area in hectares = (1m^2=10000hectare)

Area =3.5hectare
