Question

One side of a square is 540metres.calculate the distance round the field in metres and kilometres

Answer 1

Answer:

2160 and 2km 160m

Step-by-step explanation:

First we get the main answer, we use the perimeter formula of square which is 4 x side.

So, 540 x 4 =2160m

Now, we have to convert it in km and m

We know that 1 km = 1000 m.

So, we separate the last three digits and the first digit which gives us 2 160. Now we put km next to 2 and m next to 160. Which leaves us with 2km 160m as our answer.
