Step-by-step explanation:

Question :-

Find the MEASURE of sides of a triangle which are in the ratio 3:4:5 and whose perimeter is 36cm

We Have :-

Ratio 3:4:5

Perimeter of the triangle = 36 cm

To Find :-

Sides of the triangle

Formula USED :-

Perimeter of Triangle = SIDE + Side + Side

Solution :-

Let the sides be -

3x

4x

5x

Perimeter of Triangle = Side + Side + Side

36 = 3x + 4x + 5x

36 = 12 x

x = 36 / 12

x = 3

Sides are :-

3x = 3 × 3 = 9 units

4x = 4 × 3 = 12 units

5x = 5 × 3 = 15 units

Sides of the triangle respectively are 9 units , 12 units , 15 units
