Question

The area of a rectangular plot is 270 m 2 and its length is 18 m. If the cost of
fencing the park by wire is ` 25 per metre, find the total cost of fencing.

Answer 1

Answer:

• Area of plot = 270m²
• Length = 18m
• Breadth = b

First Finding Breadth:

• Area = Length × Breadth
• 270m² = 18 × b
• b = 270/18
• b = 15m

Now,

• Area = 270m²
• Cost of fencing wire/m² = ₹25
• So, cost of fencing 270m² =
• $\tt\bf\red{270 × 25 }$
• $\tt\bf\red{= ₹6750}$
