A rectangle plot of land has determinasion as 50m*30m there are 5flower beds in the plot of the size 5m*3m find the area of the remaining plots also find the cost of ploughing five flower beds at the rate of ₹30 per m2
50*30 - 5*5*3 = 1425m^2
cos: 5*(5*3)*30 = ?
To find the area of the remaining plot, we need to subtract the total area of the flower beds from the area of the whole plot.
Step 1: Find the area of the whole plot
The area of the whole plot is calculated by multiplying the length (50m) by the width (30m):
Area of whole plot = Length × Width = 50m × 30m = 1500m2
Step 2: Find the area of one flower bed
The area of one flower bed is calculated by multiplying the length (5m) by the width (3m):
Area of one flower bed = Length × Width = 5m × 3m = 15m2
Step 3: Find the total area of the flower beds
Since there are 5 flower beds, we multiply the area of one flower bed by 5:
Total area of flower beds = Area of one flower bed × Number of flower beds = 15m2 × 5 = 75m2
Step 4: Find the area of the remaining plots
To find the area of the remaining plots, subtract the total area of the flower beds from the area of the whole plot:
Area of remaining plots = Area of whole plot - Total area of flower beds
Area of remaining plots = 1500m2 - 75m2 = 1425m2
So, the area of the remaining plots is 1425m2.
Step 5: Find the cost of ploughing the flower beds
To find the cost of ploughing the flower beds, we need to multiply the total area of flower beds by the cost per square meter:
Cost of ploughing = Total area of flower beds × Cost per square meter
Cost of ploughing = 75m2 × ₹30/m2 = ₹2250
Therefore, the cost of ploughing the five flower beds at the rate of ₹30 per square meter is ₹2250.
