Question

find the cost of a fencing a square park of side 70 m at ruppes 15 per meter​

Answer 1

Answer

4,200 Rupees

Step-by-step explanation:

70 * 4 = 280

280 * 15 =  4200 Rupees

Answer 2

$\Large{\underline{\sf{\purple{Required\:Solution:}}}}$

Given thαt,

• Side of α squαre pαrk is 70m.
• Cost of fencing = 15 per m.

To find -

• The cost of fencing the squαre pαrk.

Procedure -

In this question, we αre asked to find the cost of fencing α squαre pαrk. To do so, firstly we need to find the perimeter of the squαre pαrk αnd then multiply it with Rs 15.

So let's do it! :D

Knowledge Required -

$\large\star{\boxed{\sf{\purple{ Perimeter_{(square)} = 4\times (side)}}}}$

Step by step explαnαtion -

• Substitute the vαlues in the formulae written αbove αnd simplify.

$\longrightarrow{\sf{ 4 \times (70cm)}}$

$\longrightarrow{\sf{ 280cm}}$

Therefore, the perimeter of the square is 280cm.

Now,

• Multiply the perimeter with the rate of fencing.

$\implies{\sf{ 280\times 15}}$

$\large\implies{\boxed{\sf{\purple{ Rs.4200}}}}$

Hence, the cost of fencing the squαre pαrk is Rs.4200.

And we αre done! :D
