Question

The side of square field is 300m.Find it's perimeter in km.​

Answer 1

Answer:

Perimeter of square =1.2km

Step-by-step Explanation:

Given:

Length of square field=300m

To find:

Perimeter of square field

Solution:

In this question, we have to find perimeter of square. Perimeter is basically sum of all sides of a given figure. We have certain formulae for different figures to find perimeter. So let's apply formula for perimeter of square.

Let's do it!!

★ Perimeter of square=4×Side

Perimeter of square=4×300m

Perimeter of square=1200m

So the perimeter of square is 1200 metre.

We are asked to find perimeter in km. So let's convert this scale in km.

1000m=1km

$\sf 1m=\dfrac{1}{1000}km$

$\sf 1200m=\dfrac{1}{1000}\times 1200\:km$

$\sf 1200m=\dfrac{1200}{1000}\:km$

$\sf 1200m=1.2\:km$

So the required perimeter of square is 1.2km.

More formulae:

• Perimeter of rectangle=2(L+B)

• Perimeter of rhombus=4×Side

• Area of rectangle=Length×Breadth

• Area of square=Side²

• Area of ||gm=Base×Height

• Area of triangle=½×Base×Height
