Answer 2

Answer :

The required cost of fencing the square park of side 75 m at ₹ 16 per meter is ₹4800

Step-by-step explanation :

Given :

• Side of the square park = 75 m

• Cost of fencing per meter = ₹ 16

To find :

the cost of fencing the square park

Solution :

 $\setlength{\unitlength}{1cm}\begin{picture}(0,0)\thicklines\multiput(0,0)(4,0){2}{\line(0,1){4}}\multiput(0,0)(0,4){2}{\line(1,0){4}}\put(1.5,-0.6){\bf\large 75 m}\put(4.4,2){\bf\large 75 m}\put(1.2,2){\large \sf square park}\end{picture}$

 Let's find the perimeter of the square park.

 Perimeter of the square park = 4 × (side of the square park)

➙ Perimeter of the square park = 4 × (75 m)

➙ Perimeter of the square park = 300 m

Now, we're given the cost of fencing per meter.

For one meter, the cost of fencing is ₹ 16

For 300 m , the cost of fencing

  = ₹ 16 × 300

  = ₹ 4800

∴ The cost of fencing the square park of side 75 m at ₹ 16 per meter is ₹4800
