Question

A rectangular garden is 175 m long and 96 m broad. Find the cost of fencing it at the rate of 18.50 per meter. Also, find the cost of ploughing it at the rate of 5.50 per square meter.​

Answer 1

AnSwer -:


____________________________


Cost of fencing of the rate Rs 17.5 per m

= Rs 9,485


Cost of ploughing of the rate Rs. 4.5

paise per m = Rs 75,600

______________________________

Area of Rectangle-:

Length x breadth


Perimeter of the rectangle

= 2( length + breadth )

______________________________

Explanation-:

Given ,

Length of rectangular garden = 175 m

Breadth of rectangular garden = 96 m

We know formula-:

Perimeter of the rectangle

= 2( length + breadth )


Therefore,

Perimeter of rectangular garden =

⇒ 2( 175 + 96)

⇒ 2 ( 271 )

⇒ 542 m


Then ,

Perimeter of rectangular garden = 542m

Then,

Cost of fencing = rate of fencing x

perimeter to be fenced

Cost of fencing = 17 .5 per m


Cost of fencing = 542 m x 17.5

Cost of fencing = Rs 9,485


Also ,

To find ,

Cost of ploughing

So ,

We know that ,

Area of Rectangle-:

Length x breadth

So ,

Area of garden = 175 m x 96 m

Area of the garden = 16,800 m^2

Hence,


Cost of ploughing = rate of ploughing x

area to be ploughed


Cost of ploughing = Rs 4.5 / m^2 x

16800 m^2

Cost of ploughing = Rs 75,600
