Answer 1

Step-by-step explanation:

total cost of fixing a fence is = Rs 28000

rate of fixing a fence is = Rs 25 per meter

total cost = rate × perimeter

28000 = 25 × perimeter

perimeter = 1120m

4s = 1120

s = 280

area = s² = 280×280 = 78400m²

Answer 2

Given :

The cost of fixing a fence around a square field is rs. 28.000. if the rate of fixing the fence is rs. 25 per metre.

To find :

• The perimeter of the square field.
• The area of the field.

Solution :

• Total cost of fixing a fence around a square field = Rs.28000

• Rate of fixing = Rs.25

→ Perimeter of square field

→ Total cost/Rate of fixing

→ 28000/25

→ 1120 m

•°• Perimeter of square field = 1120m

________________________________

• As we know that

→ Perimeter of square = 4a

• Where " a " is side

→ 1120 = 4a

→ a = 1120/4

→ a = 280 m

• Area of square

→ Side × side

→ 280 × 280

→ 78400m²

•°• Area of square = 78400
