The correct terminology is "height," not "high."

Also, the shape is called a "triangle," not a "tringle." Don't worry! English is a difficult language to use and learn! It just takes time.

Of course , Learning New language alway's difficult.
Also spelling mistake in this problem not from me.
This problem has written by my little brother.
The next problem after this has written by me.
The area of a triangle is given by A = 2 1 b h where b is the base and h is the height. Substitute:
3 0 = 2 1 ( 3 ) h
h = 2 0 cm

Area = 2 B a s e × H e i g h t
Height = B a s e A r e a × 2
Base = H e i g h t A r e a × 2
Hence the answer is 2 0
