Question

if the perimeter of traingle PQR is 40 cm and the ratio of its sidy is 1: 3: 4 find the sides of traingle​

Answer 1

Answer:

A= 5 cm

B= 15 cm

C = 20 cm

Step-by-step explanation:

Let A = 1x

B = 3x

C = 4x

perimeter of triangle =A+B+C

40 = 1x+ 3x+4x

40= 8x

x = 5

A= 1*5 =5cm

B= 3*5 = 15 cm

C = 4*x = 20cm
