Question

fencing at < 50 per metre?
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

☆ Given :

• Perimeter of a square field = 480 m

☆ To find :

• The length of its side.
• The area of the field.

☆ Solution :

Finding the side of the square.

★Perimeter of square = 4 × side

↦ 480 = 4 × side

↦ 480/4 = side

↦ 120 = side

↦ side = 120 m

Now, finding the area of the square.

★Area of Square = side × side

↦ Area (square) = 120 × 120

↦ Area (square) = 14400 m²

Therefore,

• Length of side of square is 120m.
• Area of square is field is 14,400m².

Answer 2

Answer:

side=120m, area=14400sq.meter

Explanation:

perimeter=4×side

480= 4×side

480/4= side

120=side

side=120

area of square= side×side

=120×120

=14400sq.meter
