Question

o The perimeter of a triangle is 40 cm. If one side of triangle is 10 cm more than the smaller side and second is double of the smallest side. Find the length of 3 sides of triangle.​

Answer 1

Answer:

let one side=x

second side=x+10

third side=2x

perimeter=40 cm

x+x+10+2x =40

4x+10=40

4x=30

x=30/4=7.5cm

x=7.5 cm

second side=7.5+10=17.5cm

third side=2*7.5=15cm
