Question

triangle ABC similar to triangle PQR. A(triangle ABC) : A ( triangle PQR) = 64 . find the ratio of their corresponding height​

Answer 1

QR = 5 cm  if  ΔABC ≈ Δ PQR  Area of Δ PQR = 100 cm² Area of ΔABC = 64 cm² & BC = 4 cm

Step-by-step explanation:

ΔABC ≈ Δ PQR

Area of Δ PQR  / Area of ΔABC  =  (PQ/AB)²  = (QR/BC)²  = (PR/AC)²

Area of Δ PQR = 100 cm²

Area of Δ ABC = 64 cm²

BC = 4 cm

QR = ?

Area of Δ PQR  / Area of ΔABC  =   (QR/BC)²

=> 100 /64  =  (QR/4)²

=>  25 / 16  = QR²/16

=> QR² = 25

=> QR = 5 cm

Answer 2

Step-by-step explanation:

This is very simple answer is QR=5
