Question

Find the area of a triangle whose sides are 18cm 24cm and30cm also find the length of altitude corresponding to the largest side of the triangle

Answer 1

Answer:

216 cm^2 , 34.98cm

Step-by-step explanation:

half perimeter = a+b+c / 2 = 18 +24 +30 / 2 =36cm = s

area of triangle= {s*(s-a)*(s-b)*(s-c)}^0.5

= { 36*18*12*6}^0.5

= 216 cm^2

altitude length corresponding to largest side of triangle = (30^2 +18^2) = 34.98cm
