A wire is 7x-3 metres long. A length of 3x-4 metres is cut for use. How much wire is left out . If this left out wire is used for an equilateral triangle. What is the length of each side of the triangle

Dear Student,

Total wire left =7x-3-3x-4 4x+1
This left out wire is to be used in equilateral triangle. each side of equilateral triangle is equal hence perimeter =3s.
The perimeter will be same as the length of left out wire.
3s=4x+1side of triangle=4x+13
