Question

3. A square field has a perimeter of 480 m. What is the length
of its side? Find the area of the field.
​

Answer 1

Answer:

perimeter of the square = 480m

4× side = 480

side= 480/4

side = 120m

Area of the square= side× side

= 120 × 120

=14400m^2

Answer 2

Given that:

• A square field has a perimeter of 480 m.

To Find:

• What is the length of its side?
• Find the area of the field.

Formula used:

• Perimeter of a square = 4 × Side
• Area of a square = Side × Side

Finding the side of the square:

According to the question.

ㅤ↠ㅤ480 = 4 × Side

ㅤ↠ㅤ4 × 120 = 4 × Side

Cancelling 4 both sides.

ㅤ↠ㅤ120 = Side

ㅤ↠ㅤSide = 120

Finding the area of square:

ㅤ↠ㅤArea = 120 × 120

ㅤ↠ㅤArea = 14400

Hence,

• The length of the side of the square is 120 m.
• Area of the square is 14400 m².
