Answer 2

Answer:

Length of square field is 10cm

Step-by-step explanation:

Given:

• Area of square field=100cm²

• Perimeter of field=40cm

To find:

• Length of field

Solution:

Let's apply formula for area of square!

Area of square field=side²

⇒ 100cm²=side²

⇒ √100cm²=Side

⇒ 10cm=Side

So the required length of side is 10cm

Alternate method:

Let's apply formula for perimeter of square!

Perimeter of square=4×Side

⇒ 40cm=4×Side

⇒ 40cm/4=Side

⇒ 10cm=Side

So the required length of side is 10cm.
