Question

find the cost of fencing rectangular park of length 175 m and breadth 150m at the rate of ₹ 12 per meter.​

Answer 1

Answer:

Length of rect. park = 175 m

Breadth of rect. park = 150 m

Length of fencing = perimeter = 2(175 + 150)

= 650 m

Rate of fencing = ₹12/m

Total cost of fencing = 650 × 12

= ₹7800 Ans...

Answer 2

❏ Question:-

find the cost of fencing rectangular park of length 175 m and breadth 150m at the rate of ₹ 12 per meter.

❏ Solution:-

$\setlength{\unitlength}{0.78 cm}\begin{picture}(12,4)\thicklines\put(5.6,9.1){ A }\put(5.5,5.8){ B }\put(11.1,5.8){ C }\put(11.05,9.1){ D }\put(4.5,7.5){ 150\:m }\put(8.1,5.3){ 175\:m }\put(11.5,7.5){ 150 \:m }\put(8.1,9.5){ 175\:m }\put(6,6){\line(1,0){5}}\put(6,9){\line(1,0){5}}\put(11,9){\line(0,-1){3}}\put(6,6){\line(0,1){3}}\end{picture}$

✏ Given:-

• length =175 m.
• breadth = 150 m.

✏ To Find:-

•cost of fencing at the rate of 12 Rs /metre.

✏ Explanation :-

$\sf\implies Perimeter=2\times(length+breadth)$

$\sf\implies Perimeter=2\times (175+150)\:m$

$\sf\implies Perimeter=2\times 325\:m$

$\sf\implies \boxed{\red{\large{Perimeter=650\:m}}}$

∴ Therefore Cost of fencing at the rate of

∴ Therefore Cost of fencing at the rate of 12 Rs/m is ,

∴ Therefore Cost of fencing at the rate of 12 Rs/m is , = (650×12) Rs.

= 7800 Rs.
