Question

the area of rectangular park is 456 m and it length is 24 m find the breadth of the park and the coast of fencing it at the rate of rs8.50 per meter

​

Answer 1

$\huge\purple{Required \: Answer :}$

Given :

Area - 456 m

Length - 24 m

Solution :

Let's Find the Breadth, Let It Be x,

Area = Length × Breadth

$456 = 24 \times x \\ x = \frac{456}{24} \: \: \: \: \: \: \\ x = 19 \: m \: \: \: \: \:$

$\huge{Breadth - 19 m}$

Now, Let Find Out Cost Of Fencing,

Fencing of an area refers to its perimeter, Hence,

Perimeter = 2 ( length + breadth)

$p = 2(24 + 19) \\ p = 2 \: ( \: 43 \: ) \: \: \: \: \: \: \\ p = 86 \: m \: \: \: \: \: \: \: \: \: \:$

Cost of Fencing -

$= 8.50 \times 86 \\ = 731 \: \: \: \: \: \: \: \: \: \: \:$

Hence, Cost of Fencing is $\huge{731 ₹}$ .

Answer 2

Answer:

Width = 19m

Peri. of the rectangle = 86m

Cost of fencing the rectangle = 731 Rs

Step-By-Step explanation:-

Length of rectangular park=24m

Area of park=456m sq.

Width=Area / Length

         =456/24

         =19m Ans.

Peri. of rectangle park= 2( l + b )

                                     = 2 ( 19 + 24 )

                                      = 2x43

                                      =86m

Now,

        Cost of fencing rectangular park = 8.50 x 86

                                                                =731 Rs Ans.
