Correct Answer:
Option A —
1080 m
Step-by-Step Calculation:
1. Define the variables using the given ratio:
The ratio of the length (L) and breadth (B) is 5:4. We can express them as:
Length (L) =5x
Breadth (B) =4x
2. Use the difference to find the value of x:
We are told that the breadth is 60 m less than the length:
L−B=60
Substitute the ratio values:
5x−4x=60
x=60
3. Calculate the actual length and breadth:
L=5×60=300 m
B=4×60=240 m
4. Calculate the perimeter:
The formula for the perimeter (P) of a rectangle is 2(L+B):
P=2(300+240)
P=2(540)
P=1080 m
Final Result:
The perimeter of the plot is 1080 m.
