Question

In triangle ABC, height AC = 3 cm. Its
area is 9 cm^2. Its basé BC =​

Answer 1

Answer:

Base = 6 cm

Step-by-step explanation:

Height = 3 cm

Area = 9 cm²

Area = 1/2 x base x height

9 = 1/2 x base x 3

9 x 2 = 3 x base

18 = 3 x base

Base = 18/3

Base = 6 cm

Answer 2

area of triangle = half × base × hight so, 9 cm= 1/2 × base× 3 cm

now' 9×3/2 = base

so, 27/2 =base

so, base = 13.5 cm
