A rectangular plot of land measures 95m by 72m.Inside the plot, a path of uniform width 3.5m is to be constructed all around.The rest of the plot is to be laid with grass.Find the total expense involved in constructing the path at rupees 46.50 per m^2 and laying the grass at rupees 3.75 per m^2.
Answers
Find the are of the rectangular plot:
Area = Length x Breadth
Area = 95 x 72 = 6872 m²
Find the area of the grass patch:
Length = 95 - 3.5 - 3.5 = 88 m
Breadth = 72 - 3.5 - 3.5 = 65 m
Area = Length x Breath
Area = 88 x 65 = 5720 m²
Find the area of the path:
Area of the path = 6872 - 5720 = 1152 m²
Find the cost of the path:
1 m² = Rs 46.50
1152 m² = 46.50 x 1152 = Rs 53568
Find the cost of the grass patch:
1m² = Rs 3.75
5720 m² = 3.75 x 5720 = Rs 21450
Find the total cost :
Total cost = 21450 + 53568 = Rs 75.136
Answer: The total cost is Rs 75.136
Answer:
Step-by-step explanation:
Area of rectangle = 6840 square metre
area of grass patch = 5720 square metre
area of path= 1120 square metre
cost of grass patch= Rs 3.75*5720=Rs 21450
cost of path =Rs46.50*1120=RS 52080
total cost=Rs 73530
