✯Question
The length and breadth of a rectangular plot are 900 m and 700 m respectively. If three rounds offence is fixed around the field at the cost of Rs. 8 per metre, what is the total amount spent?
✯Answer
Total amount = Rs.76800
Step by step explanation
Length = 900m
Breadth = 700m
Perimeter of a rectangle = = 2(length + breadth)
Perimeter of a rectangular plot
= 2(900 + 700)m
= 2(1600)m
= 3,200m
Perimeter of the rectangular plot = 3,200m
Perimeter for 3 rounds fence
= 3 × 3,200m
= 9,600m
Cost of 1 metre = ₹8
Cost of 9,600m = 9600 × 8 = 76,800
