Question

A rectangular field is $65\text{m}$ long and $45\text{m}$ wide . Find the cost of turfing it at $₹2$per square meter . Also find the cost of fencing it at $₹4$ per meter ?

Answer 1

Step 1: Finding the cost of turfing

Length of the rectangular field $=65\text{m}$

Width of the rectangular field $=45\text{m}$

Area of the rectangular field $=\text{length×width}$

$=65\times 45=2925{\text{m}}^2$

Cost of turfing it per ${\text{m}}^2\text{=}$ $₹2$

Cost of turfing $2925{\text{m}}^2\text{=2925×₹2=₹5850}$

Hence, cost of turfing is$₹5850$

Step 2: FInding the cost of fencing

For finding the cost of fencing, we need to find the perimeter of the field.

We know that, perimeter of the rectangle $=2\times (\text{length+breadth)}$

So perimeter of field $=2\times (65+45)=2\times 110=220\text{m}$

Cost of fencing per meter $=$$₹4$

Cost of fencing $220\text{m =220×₹4=₹880}$

Hence, cost of fencing is$₹880$
