    Solution:

    Given:
    Lateral side of the triangle: Base side of the triangle: Perimeter The perimeter of the triangle is equal to the sum of all the three sides of the triangle.
    Thus, Simplify, we get,
    Semi-perimeter is half of the perimeter:
    Now, using the Heron’s formula:
    Simplify the above equation:
    Hence, the area of the triangle is:
