The perimeter of a scalene triangle is 14.5 cm. The longest side is twice that of the shortest side. Which equation can be used to find the side lengths if the longest side measures 6.2 cm?

Respuesta :

SJ2006

Perimeter of scalene triangle = a+b+c (where they are sides)

c=6.2 (given)

a=3.1

so, 14.5 = 3.1+b+6.2

b=5.2

In that way, sides will be 3.1cm, 5.2cm & 6.2cm
