Web23 jul. 2024 · We know, " If two triangles are similar, then the ratio of area of both triangles is proportional to the square of the ratio of their corresponding sides ." Here, ΔADE = 45 cm², DE = 6cm, and BC = 8 cm ⇒ 45cm²/ΔABC = 6²/8² = 36/64 = 9/16 ⇒ ΔABC = 80 cm² Therefore the area of triangle ABC is 80cm².
