The formula for the area of a triangle is 1/2 times the base times the height.

Area= 1/2bh

Let's try it!

The base of this triangle is 10, the height is 7.

A= 1/2xbxh

A= 1/2 x 10 x 7

A= 35 square units

Multiple Choice

What is the area?

Multiple Choice

The triangle has base b=5 meters and height h=4 meters what is the area?

Multiple Choice

P= a+b+c

P= 3+6+4

P= 13cm

Easy right? Let's do some practice problems :)
