The perimeter of a triangle is 75cm how long is each side if they are in the ratio 7:5:3? i also need the solution pls! thankyou :)

Sagot :

7x + 5x + 3x = 75 cm

15x = 75 cm  
 15      15

x = 5 cm

With the ratio 7:5:3, the length of the sides are:
7(5 cm) = 35 cm
5(5 cm) = 25 cm
3(5 cm) = 15 cm

To check:
35 cm + 25 cm + 15 cm = 75 cm
