The perimeter of a rectangle is 151m.If the breadth is 29.5m find its length

To find the length of the rectangle, we can use the formula for the perimeter of a rectangle:

\[ \text{Perimeter} = 2(\text{Length} + \text{Breadth}) \]

Given:
- Perimeter = 151 meters
- Breadth = 29.5 meters

We can plug these values into the formula and solve for the length (L).

\[ 151 = 2(L + 29.5) \]

First, divide both sides by 2:

\[ \frac{151}{2} = L + 29.5 \]

\[ 75.5 = L + 29.5 \]

Next, subtract 29.5 from both sides:

\[ 75.5 - 29.5 = L \]

\[ 46 = L \]

Therefore, the length of the rectangle is 46 meters.
