Answer 1

Solution!!

The length and area of a rectangular lawn is given in the question. We have to find the breadth, perimeter and the cost of fencing the lawn at Rs 34 per metre.

Length = 39 m

Area = 507 m²

First of all, we will find the breadth of the lawn.

Area = Length × Breadth

507 = 39 × Breadth

Breadth = 13 m

As we have both the length and breadth, we can find the perimeter of the lawn.

Perimeter = 2(Length + Breadth)

Perimeter = 2(39 + 13)

Perimeter = 2 × 52

Perimeter = 104 m

Now that we know the perimeter, we can find the cost of fencing the lawn.

Cost of fencing 1 m = Rs 34

Cost of fencing 104 m = Rs 34 × 104

Cost of fencing the lawn = Rs 3536
