    Answer:

    25.98units³

    Step-by-step explanation:

    Area of the triangular prism = Base Area * Height of the pyramid

    A = BH/3

    Get the area of the triangle

    Area of the triangle = 1/2 Base * height

    Base of the triangle = 5

    height = √5²-2.5²

    h = √25-6.25

    h = √18.75

    h = 4.33

    Area of the triangle = 1/2 * 4.33 * 5

    Area of the triangle = 10.82

    Base area = 10.82

    Get the area of the triangular pyramid

    Area of the triangular pyramid = 10.82*7.2/3

    Area of the triangular pyramid = 25.98units³

    Hence the area triangular pyramid is 25.98units³
