Assuming the equation is asking us for Area...

Area of a triangle is:

A = [tex] \frac{1}{2} [/tex]b*h

with b = base
and h = height

so area = (0.5)(3.5)(4.5)

             =7.875 ft^2

*NOTE: not sure how to show area in feet and also brainiest answer would be nice  :D

You're finding area which is 1/2(b(h)) so it's 1/2(3.5(4.5)) = 1/2(15.75) = 7.875 (which is 7 7/8) feet squared of course. Thanks for letting me help!
