area of a triangle is one half the base times the height

(side a x side b) / 2 for a right triangle; otherwise, bisect the triangle, take the measurement of the bisecting line, multiply by the measurement of the line to which it is perpendicular and divide by 2
I believe -- it's been a long time since sophomore geometry.

if you mean area by square feet then this is the formula :
.5bh
b= base
h = height

Area= 1/2bh

All those 1/2 b*h are assuming that your b and h values are in feet. If not, convert them first.

it depends on what kind of triangle it is
Right Triangle Area = (ab)/2
Equilateral Triangle Area = a^2 * sqrt(3)/4
Isosceles Triangle Area =
b * sqrt(4a^2 - b^2)/4 =
a^2 * sin(B)/2 =
ab * sin(A)/2
Scalene Triangle Area =
(ah)/2 =
ab * sin(C)/2 =
(a^2 * sin(B) * sin(C))/[2 * sin(A)] =
sqrt[s(s - a)(s - b)(s - c)]
