Answer:
Area of Triangle = 84 cm^2
Altitude = 11.2 cm
Step-by-step explanation:
Using Heron's Formula:
Area of a triangle is equal to:
where s is the semiperimeter and (a,b,c) are the sides of the triangle.
s = (a+b+c)/2
s = (13+14+15)/2
s = 21
Substituting to the formula..
=
To solve for the Altitude, the formula is:
h_b = (2A)/b
h_b = [2(84)]/15
h_b = 11.2
