Answer: 3
Step-by-step explanation:
In the given figure , we have a triangle with side lengths 3t, 4t , 7t+6.
Also, the perimeter of triangle is given to be 48 units.
[tex]\Rightarrow\ 3t+4t+7t+6=48[/tex] [Perimeter is the sum of all sides.]
[tex]\Rightarrow\ 14t+6=48[/tex]
Subtract 6 from both the sides , we get
[tex]14t=42[/tex]
Divide 14 from both the sides , we get
[tex]t=3[/tex]
Hence, the value of t =3
