Question

F the three altitudes of a triangle are 12, 9.6 and 16, what is the area of the triangle?

Answer 1

a triangle have not 3 altitudes
I think you mean length of the triangle
then we know the area of the triangle is
A=✓s(s-a)(s-b)(s-c)
here a,b and c are length of the triangle and s=½(a+b+c)
your answer is 13.24 unit²
