Question

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

Answer 1

Given :-

Area of rectangular park = 270 m²

Length of rectangular park = 18 m

Coat of wire whose , fancing the park = ₹ 25 per m

To Find :-

Total cost of wire of fencing

Explanation :-

Using Formula

★Area=(Length×Breadth)

➽ Area of rectangular park = 270

➽ Length × Breadth = 270

Keep Value of Length,

➽ 18 × Breadth = 270

➽ Breadth = 270/18

➽ Breadth = 15 m

-------------------------------------------------------------------

Now, Calculate perimeter of rectangular park

★Perimeter=2×(Length+Breadth)

➽ Perimeter of park = 2×(Length+Breadth)

➽ Perimeter of park = 2 × (18 + 15)

➽ Perimeter of park = 2 × (33)

➽ Perimeter of park = 66 m

-------------------------------------------------------------------

⇒ Cost of fencing wire of 1 meter = ₹ 25

⇒ Cost of fencing wire of 66 meter = 25 × 66

⇒ Cost of fencing wire of 66 meter = ₹ 1650

∴ Total Cost of fencing wire will be = ₹ 1650
