Question

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

Answer 1

Answer:

Step-by-step 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
