The length of a side of a triangle is 6 cm. the second side is twice the third side. if the primeter of the triangle is 18 cm,find the side of a triangle
- length=6cm
- Let the 3rd side be x,
- then second side will be 2x
- perimeter=18cm
† perimeter = sum all sides of triangle
→ 18=x+2x+6
→ 18=3x+6
→ 18-6=3x
→ 12=3x
→ 12/3=x
→ 4cm=x
→ 2x=2×4
→ 8cm
- Second side = 4cm
- Third side = 8cm respectively
