What is the area of △ABC (in square cm) if AD is the median and area △ADB= 1

Question

What is the area of

△ A B C

(in square cm) if AD is the median and area

△ A D B

= 18 square cm?

Answer:
:

A median of the triangle divides it into two triangles of equal area.
So, Area (

△ A B C

) = 2 × Area (

△ A D B

) = 2 × 18 = 36 square cm.
