Question

How many hectares of land are there in a field that is 450 m long and 1200 dm wide.​

Answer 1

Explanation:

Given

`Length = 450\ m`

`Width = 1200\ m`

Required

Determine the number of hectares in this dimension

First, we need to calculate the area of the land

`Area = Length * Width`

`Area = 450m * 1200dm`

Convert dm to m

`Area = 450m * 120m`

`Area = 54 000 m^2`

`1 hectare = 0.0001m^2`

So, we have:

`1\ hectare = 0.0001m^2`

Multiply by 54000

`Hectare = 0.0001 * 54000`

`Hectare = 5.4`

Hence, there are 5.4 hectares
