    Answer:

    Perimeter=737 feets

    Area=13542.6 ft²

    Step-by-step explanation:

    Well assuming that a,b,c are the three sides of the triangle and h is the height then;

    Perimeter=distance around the figure

    P=164+221+352= 737 feet

    Area of a triangle given three sides is calculated using the formulae;

    Area=√s (s-a) (s-b) (s-c) where  s=(a+b+c)/2

    Finding s;

    s=(164+221+352)/2 =368.5 feet

    Finding the area

    A= √ 368.5 (368.5-164) (368.5-221) (368.5-352)

    A=√368.5 (204.5) (147.5) (16.5)

    A= 13542.6 ft²
