Question

If sum of the sides of a triangle PQR is equal
to 36 cm and PQ: QR: PR = 2:3:4, find the
length of the sides of the triangle.​

Answer 1

Step-by-step explanation:

Let the length of sides of triangle be 2x,3x and 4x respectively.

So, 2x+3x+4x = 36

9x = 36

x = 36/9

x = 4

So, 2x = 2×4= 8cm

3x = 3×4= 12cm

4x= 4×4= 16cm

So length of sides of triangle is 8cm,12cm and 16cm respectively.
