Question

एक खेत 140 मीटर लंबा तथा 100 मीटर चौड़ा हैं इसमे चारो ओर रू5.25 प्रति मीटर की दर से काँटेदार तार लगवाने पर खर्च ज्ञात कीजिए​

Answer 1

Solution:

Given

• Length of field = 140 m
• Breadth of field = 100 m

Now, According to the Question's Statement!

We have to find the Perimeter of field;

Perimeter = 2(l+b)

Perimeter = 2(140 + 100 )

Perimeter = 2(240)

Perimeter = 480 m

Now, We have to find the cost of fencing at the 5.25.

Cost of Fencing = Perimeter × 5.25

Cost of fencing = 480 × 5.25

Cost of fencing = 2520

Therefore, Cost of fencing is 2520
