Study the given figure and answer the question that follows.
Find the length of AB in the given triangle, if it is given that the length of BD is 4 unit.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 4 units
Given that
The length of BD is 4 unit
As we know From the similar triangle ABC and ADE
AB/AD = BC/DB = 3/6 = 1/2
AD = 2 AB
AD = AB + BD = AB + 4
Hence, AB + 4 = 2 AB
AB = 4 units
