Problem Setup:
- Let the length of the rectangular field be $L$ and the breadth be $B$.
- The ratio of length to breadth is given as $L : B = 6 : 5$.
- We can represent the length as $L = 6x$ and the breadth as $B = 5x$ for some common multiplier $x$.
- It is stated that the breadth is 25 m less than the length, which means $B = L - 25$ or $L - B = 25$.
Finding the Dimensions
Substitute the expressions for $L$ and $B$ in terms of $x$ into the difference equation:
$L - B = 25$
Substituting $L = 6x$ and $B = 5x$:
$6x - 5x = 25$
Solving for $x$:
$x = 25$
Now, calculate the actual length and breadth:
- Length $L = 6x = 6 \times 25 = 150$ m
- Breadth $B = 5x = 5 \times 25 = 125$ m
Check: The difference $L - B = 150 - 125 = 25$ m, which matches the given information.
Calculating the Perimeter
The formula for the perimeter $P$ of a rectangle is:
$P = 2(L + B)$
Substitute the calculated values of $L$ and $B$:
$P = 2(150 \text{ m} + 125 \text{ m})$
$P = 2(275 \text{ m})$
$P = 550 \text{ m}$
Therefore, the perimeter of the field is 550 m.
