    Answer:

    Step-by-step explanation:

    Remark

    This is a right angle triangle.

    Proof

    a^2 + b^2 = c^2

    a = 3

    b = 4

    c = 5

    3^2 + 4^2 = 5^2

    9 + 16 = ? 25

    25 = 25

    Area

    The 2 smaller legs are perpendicular to each other.

    Area = 1/2 a * b

    Area = 1/2 * 3 * 4

    Area = 6
