Question

if the area of the triangle ABC is 36cm sq. and the height ad is 4cm, then the base bc=what​

Answer 1

Answer:

18cm

Step-by-step explanation:

area of triangle=1/2×b×h

36=1/2×b×4

36=4b/2

36=2b

2b=36

b=36/2

b=18cm

therefore base=bc=18cm

Answer 2

Answer:

according to the question

area of triangle = 1/2 ✖ height ✖ base

36=1/2 ✖ 4 ✖ x( let the base be x)

transpose 1/2 to lhs

36 ✖ 2/1=4 ✖ x

72=4 ✖ x

transpose 4 to lhs

72 ➗ 4= x

18=x

Thus base = 18 cm
