Find the height of the triangle by applying formulas for the area of a triangle and

lina2011 [118]

Answer:

Step-by-step explanation:

a= 12 mm ; b = 16 mm ; c = 18 mm

s = (a + b+c)/2

$=\dfrac{12 + 16 + 8}{2}\\\\= \dfrac{36}{2}\\\\= 18\\\\$

s -a = 18 - 12 = 6 mm

s -b = 18 - 16 = 2 mm

s -c = 18 - 8 = 10 mm

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

$= \sqrt{18*6*2*10}\\\\= \sqrt{2160 }\\\\=46.47\\\\=46 \ mm^{2}\\$

$\dfrac{1}{2}* \ base * \ height = 46\\\\\dfrac{1}{2}*16* \ height = 46\\\\height = \dfrac{46*2}{16}\\\\$

= 5.75

Height = 5.8 mm
