The value of t = 2. <u>Option a)</u> 2 is the correct answer.
<u>Step-by-step explanation:</u>
Perimeter is the sum of three sides of a triangle.
Given that, the points D and E are midpoints of the sides.
Therefore,
side AB= AD+DB
AB= 3t + 3t = 6t
side BC= BE+EC
BC= 4t + 4t = 8t
side AC= 7t+6
Perimeter of the triangle= sum of (side AB+side BC+side AC)
48 = 6t+8t+7t+6
48 = 21t+6
t= 42/21
t= 2
