Answer:
T = 2.
Explanation:
Since we only have half the side lengths for AB and BC, we need to multiply those by 2. This gives us AB = 6t and BC = 8t.
6t + 8t + 7t + 6 = 48.
Subtract 6 from both sides of the equation. This gives us 6t + 8t + 7t = 42.
Add all the variables together for 21t = 42.
Divide by 21. t = 2.
That's the value of T.
