If L is the mid-point of side BC of △ ABC and the area of…

If L is the mid-point of side BC of $\triangle$ ABC and the area of $\triangle$ ABL is 15 cm², then the area (in sq cm) of $\triangle$ ABC is:

Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2 i.e. 30.

L is the midpoint of side BC of ΔABC

Area of ΔABC = 2 × Area of ΔABL = 2 × 15 = 30 cm²

Therefore, the area of tΔABC is 30 cm².
