What is the length of the shortest
side. If the perimeter of the triangle in 30 cm?
no correct alternatives​

Answer 1

Step-by-step explanation:

let the ratios be x

therefore, A= 1/2x

B= 2/3x

C= 1/3x

so, 1/2x + 2/3x + 1/3x = 30

9x/6 = 30

x= 45

length of 1/2 = 22.5 cm

length of 2/3 = 30 cm

length of 1/3 = 15 cm

ANS... the length of shortest side is 1/3 i.e. 15 cm
