Answer 1

Answer:

PN = 4.8 cm

Step-by-step explanation:

Given:

Area of ΔABC = 100 cm² and Area of ΔPQR = 144 cm²

It is said that ΔABC is similar to ΔPQR.

We know that,

If two triangles are similar, then the ratio of the area of both triangles is proportional to the square of the ratio of their corresponding sides.

So,

Area of ΔPQR/Area of ΔABC = (PN/AM)²

⇒ (144/100) = PN²/4²

⇒ 16 * 144 = PN² * 100

⇒ 2304 = PN² * 100

⇒ PN² = 23.04

⇒ PN = 4.8 cm

Therefore,

PN = 4.8 cm

Hope it helps!
