    Answer:

    The area of the resulting triangle will be: \boxed{A=900\:cm^2\:}

    Step-by-step explanation:

    The area of a triangle is

    A=\frac{1}{2}\times base\times height

    Let us suppose

    • base = 4 cm
    • height = 18 cm

    A=\frac{1}{2}\times base\times height

    A\:=\frac{1}{2}\times \:4\times \:18\:\:\:\:\:

    A=36\:cm^2\:

    As the base and height are scaled a factor of 5.

    so

    base = 4 × 5 = 20

    height = 18 × 5 = 90

    as

    A=\frac{1}{2}\times base\times height

    A\:=\frac{1}{2}\times \:20\times \:90

    A=900\:cm^2\:

    Therefore, the area of the resulting triangle will be: \boxed{A=900\:cm^2\:}
