Answer 2

Question:

The rectangle XYZW shows Ravi's garden. Ravi puts a fench around three sides of the garden, XY, YZ and ZW. The fench costs ₹7 per meter. Find the total cost of the fencing.

Given:

✰ XYZW is a rectangular garden.

✰ Ravi puts a fench around three sides of the garden, XY, YZ and ZW.

✰ XY = 30 m

✰ YZ = 15 m

✰ The fench costs ₹7 per meter.

To find:

✠ The total cost of the fencing.

Solution:

Let's understand the concept first! We know Ravi puts a fench around three sides of the garden, XY, YZ and ZW, So we will find the length of their boundaries by adding XY, YZ and ZW. XY and YZ are already given to us, whereas, ZW is 30 m because opposite sides of rectangle are equal, so it is equal to XY. Now, after adding them all we will find the total cost of the fencing these boundaries i.e, three sides of the garden.

Let's find out...♪

The perimeter of a closed plane is the total length of its boundary, but here we will exclude XW because it is not being fenced.

➛ Length of fencing three sides of the garden = XY + YZ + ZW

➛ Length of fencing three sides of the garden = 30 + 15 + 30 [ ZW = 30 m ∵ Opposite sides of rectangle are equal ]

➛ Length of fencing three sides of the garden = 45 + 30

➛ Length of fencing three sides of the garden = 75 m

Now,

➤ Cost of fench per meter = ₹7

➤ Cost of fench per 75 m = 7 × 75

➤ Cost of fench per 75 m = ₹525

∴ The total cost of the fencing three sides of the garden = ₹525
