Since the two triangles are similar, we can set up the proportion:
BC/CA = FD/EF
42/21 = 14/EF
2 = 14/EF
EF = 14/2
EF = 7 feet
Therefore, the length of EF is 7 feet.
The two triangles above are similar. The length of BC is 42 feet. The length of CA is 21 feet. The length of FD is 14 feet.
What is the length of EF?
