Explanation:

- Given that the area of the rectangle is 96 square meters more than the area of the triangle.

- Length of the rectangle is 18 meters.

- Height of the triangle is 20 meters.

- Base of the triangle is equal to the breadth of the rectangle.

Let's find the breadth of the rectangle:

- Area of triangle = \( \frac{1}{2} \times \text{base} \times \text{height} = \frac{1}{2} \times b \times 20 = 10b \).

- Area of rectangle = \( 18 \times b \).

Given that \( 18b = 10b + 96 \):

- Solving for b: \( 8b = 96 \) which gives \( b = 12 \).

Now, calculate the perimeter of the rectangle:

- Perimeter = 2(length + breadth) = 2(18 + 12) = 60 meters.

- Correct answer: Option 1 - 60 meters
