The area of the triangle is 36 m ^ 2. Find a side if you know that the height drawn to that side is 4m.

Given:
Triangle ABC,
ВН height drawn to the AC side,
ВН = 4 meters,
S abc = 36 square meters.
Find the length of the side of the speaker -?
Solution:
Consider a triangle ABC. The area of a triangle is the product of 1/2 the height of the side to which it is drawn. Consequently:
S abc = 1/2 * ВН * AC;
36 = 1/2 * 4 * AC;
36 = (1 * 4) / 2 * AC;
36 = (1 * 2) / 1 * AC;
36 = 2 * AC;
AC = 36: 2;
AC = 18 meters.
Answer: 18 meters.
