Question

In the given figure, DE // BC. The value of EC is
a. 1.5cm
b. 3cm
c. 2cm
d. 1cm​

Answer 1

Answer:

2 cm

Explanation:

Given: DE | | BC . Hence

AD/DB

= AE/EC

[by basic proportionality theorem which states that if a line is drawn parallel to one side of a triangle the other two sides in distinct points, then the other twos sides are divided in the same ratio

⟹1.53=

EC

1

[Given: AD= 1.5cm, DB = 3cm & AE = 1cm ]

EC=

1.5

3

⟹EC=2cm
