Does the triangle have a specified type such as right angle or equilateral?
OpenStudy (anonymous):
that's all the question said, no picture as well.
OpenStudy (anonymous):
Ok let me think then
OpenStudy (anonymous):
Area = 1/2 x base x perpendicular ht
OpenStudy (anonymous):
THE IS SUPPOSED TO BE A EXPONENT RIGHT? SORRY CAPS LOCK

Thats all you need, use Area A=1/2 b h
OpenStudy (radar):
Area is in "square" units.
OpenStudy (anonymous):

OpenStudy (anonymous):
let me check then and see
OpenStudy (anonymous):
so 1/2*B*H?

Yes
60 sq yd = 1/2 12 yd h(yd)
60 yd^2 = 6 h (yd)
h = ?? yd.
