Question

the sides of a triangle are 42 CM 34 cm and 20 CM calculate its area and the length of the height on the longest side

Answer 1

Sides=34,42,20=a,b,c

Area of triangle=✓p(p-a)(p-b)(p-c)

P=(a+b+c)/2

P=96/2=48

Area=✓112896=336

Also,area is 1/2*b*h

B=42(longest side)

1/2*42*h=336

h=16
