Question

*In triangle ABC, DE || AB. If CD = 3 cm, EC = 4 cm, BE = 6 cm, then DA is equal to …………….*

1️⃣ 7.5 cm
2️⃣ 3 cm
3️⃣ 4.5 cm
4️⃣ 6 cm​

Answer 1

then DA = 4.5 cm ok

Answer 2

Given :-

• In triangle ABC, DE || AB.
• CD = 3 cm.
• EC = 4 cm.
• BE = 6 cm.

To Find :-

• DA = ?

Solution :-

we know that,

• When a line is drawn parallel to one side of a triangle to intersect the other two sides in distinct points, then the other two sides are divided in the same ratio.

given that,

• DE || AB .

so,

→ CD / DA = CE / EB

putting values we get,

→ 3 / DA = 4 / 6

→ 3 / DA = 2 / 3

→ 2DA = 3 * 3

→ DA = 9 / 2

→ DA = 4.5 cm. (3) (Ans.)
