Question

In the given figure DE||BC, if AD=3.4cm, AB=8.5cm and AC=13.5cm, find AE​

Answer 1

Answer:AE=5.4cm

Step-by-step explanation:

Since DE∥BC, from Basic Proportionality Theorem,

we have

AD÷AB=AE÷AC

∴ 3.4/8.5=AE/13.5

=>AE=(3.4×13.5)÷8.5

Hence,AE=5.4 cm

Answer 2

Answer:

The answer is AD/AB=AE/AC. AE = 2.14
