AD is 3cm.​

Answer 1

Answer:

Given :

height = 3 cm

area = 36cm2

Solution :

area of ∆ = 1÷2×b×h

36 = 1÷2×b×3

b = 36×2÷3

b = 24cm

so , BC = 24 cm.

Answer 2

Base BC of Triangle ABC is 24 cm

Step-by-step explanation:

Question :-

Find BC, if the area of the triangle ABC is 36 cm2 and the height AD is 3cm ?

We Have :-

Triangle ABC

Area = 36 cm²

Height AD = 3 cm

To Find :-

Base BC

Formula Used :-

$area \: of \: triangle \: = \: \dfrac{1}{2} \times base \times height$

Solution :-

$area \: of \: triangle \: = \: \dfrac{1}{2} \times base \times height \\ \\ 36 = \dfrac{1}{2} \times base \times 3 \\ \\ base = \dfrac{36 \times 2}{3} \\ \\ base = 24 \: cm$

Base BC of Triangle ABC is 24 cm
