Question

A rectangular park is 30 metres long and 20 metres broad. A steel wire fence is put up all around it. Find the cost of putting the fence at the rate of ₹15 per metre.​

Answer 1

Answer:

$\red\bigstar$ Cost of fencing the field at  Rs15 per meter = Rs1500.

✳SOLUTION✳

Length (l) of the rectangular park = 30 m.

Breadth (b) of the rectangular park = 20 m.

$\setlength{\unitlength}{1cm}\begin{picture}(0,0)\thicklines\multiput(0,0)(5,0){2}{\line(0,1){3}}\multiput(0,0)(0,3){2}{\line(1,0){5}}\put(0.03,0.02){\framebox(0.25,0.25)}\put(0.03,2.75){\framebox(0.25,0.25)}\put(4.74,2.75){\framebox(0.25,0.25)}\put(4.74,0.02){\framebox(0.25,0.25)}\multiput(2.1,-0.7)(0,4.2){2}{\sf\large 30 m}\multiput(-1.4,1.4)(6.8,0){2}{\sf\large 20 m}\put(-0.5,-0.4){\bf A}\put(-0.5,3.2){\bf D}\put(5.3,-0.4){\bf B}\put(5.3,3.2){\bf C}\end{picture}$

Fencing is done along the perimeter .

Perimeter of the rectangle = 2(length + breadth) = 2(l+b)

Perimeter of the rectangle = 2(30+20)

Perimeter of the rectangle = 2 × 50 = 100m.

Rate of fencing per meter = ₹15 per meter.​

∴ Cost of fencing the field at  ₹15 per meter = 15 × 100

✩ Cost of fencing the field at  ₹15 per meter = ₹1500
