Question

Q5. In AABC, DE || BC. If DB =
5.4 cm, AD = 1.8 cm and EC =
7.2 cm then find AE.​

Answer 1

Step-by-step explanation:

AD/DB = AE/EC

1.8/5.4 = AE/7.2

3*7.2 = AE

21.6 = AE

Answer 2

Answer:

AE = 2.4

Step-by-step explanation:

IN ABC

DE||BC

by basic proportionality theorem

AD/DB = AE/EC

1.8/5.4 = AE/7.2 -----cm

1.8*7.2 =5.4*AE

12.96 = 5.4* AE

AE= 12.96/5.4

AE = 2.4
