Question

, find the area of triangle whose sides are 13 cm 14 cm and 15 cm find the altitude to side measuring 15 CM​

Answer 1

Answer:

Area of the triangle is 84 cm^2

Answer 2

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:

$\sqrt{s(s - a)(s - b)(s - c)}$

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..

=

$= \sqrt{21(21 - 13)(21 - 14)(21 - 15)} \\ = 84$

To solve for the Altitude, the formula is:

h_b = (2A)/b

h_b = [2(84)]/15

h_b = 11.2
