Question

Find BC (base),if the area of triangle ABC is 36cm square and height AD is 3cm.

Answer 1

Step-by-step explanation:

area of triangle =1/2 ×base ×height

Here,height AD =3cm

area=36 cm

so,

36 =1/2 ×base × 3

36 × 2 ÷ 3 =base

12 × 2 = 24 ( as 3×12=36)

Therefore ,base of the triangle ABC = 24cm
