Question

The sides of a triangle are in the ratio 2 : 4: 5. The smallest
side is 15cm less than the largest side. Calculate the length
of all three sides.

Answer 1

Answer:

10,20,25 are the sides of triangle

Step-by-step explanation:

Let us assume the sides as 2x,3x,4x

Given the smallest side is 15 cm less than the largest side

so, 5x - 15 = 2x

5x - 2x = 15

3x = 15

x = 15/3

x = 5

Now the sides are 2x = 2*5 = 10 cm

4x = 3*5 =20cm

5x = 5*5 = 25 cm
