Question

The cost of leveling a turning a square lawn at rs 2.50m2 is rs 13322.50. Find cost of fencing it at rs 5 per meter

Answer 1

GIVEN :

• A square lawn is levelled and fenced .
• Cost of levelling it up at ₹ 2.59/m² turns out to be ₹ 13322.50

TO FIND :

• The cost of Fencing it up at ₹ 5/m²

SOLUTION :

We can conclude from seeing the question that the area of square could be divided by total cost from rate per meter as we know that area multiplied by rate per meter is total cost. so :

➠ Area of square = (Total cost/Rate)

➠Area of square = 13322.5/2.5

➠Area of square = 5329m²

Then,

➠Each side of square = √5329

➠ Each side of square = 73 m

Now,we need to find out the perimeter of the square as in the question it's talking about Fencing, and we fence the perimeter of a lawn.

➠Perimeter of the square = 73 × 4

➠Perimeter of the square = 292 m

So, The last step for solving this turns out to be multipliying the perimeter of that square with the rate of Fencing it per meter.

➠Rate of Fencing = ₹ 5/m

➠Total cost of Fencing = 5 × 292 m

➠Total cost of Fencing = ₹1460

Hence, Our answer or the cost of Fencing a square lawn is ₹ 1460

Answer 2

₹2.5 = 1 m²

₹13322.5 = (13322.5/2.5) m²

Area of square = 5329 m²

Area of square = 5329 m²

Side of square = √5329 m

Side of square = 73 m

Perimeter of square = 4 × Side

Perimeter of square = 4 × 73

Perimeter of square = 292m

Cost of fencing 1 m = ₹5

Cost of fencing 292 m = ₹(292×5)

Cost of fencing 292 m = ₹1460
