$\huge{\purple{❥}\pink{a}\orange{n}\blue{s}\red{w}\green{e}\purple{r}}$

given:-

• ratio of the length of the sides of the triangle are 3:4:5
• perimeter of the triangle =48

To find:-

• lenght of the sides of the triangle

solution:-

• so let the sides be 3x,4x,5x
• perimeter of a triangle =sum of all sides
• 48cm=3x+4x+5x
• 48cm=12x
• x=48÷12
• x=4

sides=

• 3x=3(4)=12cm
• 4(x)=4(4)=16cm
• 5(x)=5(4)=20cm

therefore the ratio of the sides are:-12:16:20cm
