Answers
Answer:
Step-by-step explanation:
Dimensions of the park = 180m length and 110m breadth.
By looking at the dimensions we determine the park is rectangular.
To find the length of wire req. to fence around it,
Perimeter of rectangle = 2 (L+B)
= 2 ( 180 + 110)
= 2 x 290
= 580
Therefore, 580 meters of wire is req. to fence the park once.
Five rows of wire are fenced around it.
Therefore, total wire req. = 5 x 580
= 2900
Therefore, 2900 meters of wire is req. to fence the park five times.
Cost of 1m of wire = 45paise
Therefore, cost of 2900 meters of wire = 45 x 2900
= 130500
Therefore, cost of wire will be 130500 paise.
Conversion of Paise to Rupees.
100 paise = 1 rupee
Therefore, 130500 paise = 130500 / 100
= 1305
Therefore, the cost of wire in rupees will be 1305.
