Question

1. Two triangles have their sides measuring 5 cm, 6 cm, 9 cm and 7.5 cm, 13.5 cm, 20.25 cm

respectively. There areas are in the ratio :
(a) 2:3 (b) 4:9 (c) 9:4 (d) 3:2
Give explannation too.​

Answer 1

Step-by-step explanation:

Area of this triangle = √{S * (S - A) * (S - B) * (S - C)} = √(20.625 * 13.125 * 7.125 * 0.375) sq cm = √723.285 sq cm = 26.894 sq cmRatio of their areas = 10 : 19 (approximately).
