Practice makes perfect

Let's find the area of the given triangle. The area of a triangle is half the product of its base and its height.

In the given triangle, we can see that the base is 18 inches and the height is 7 inches. We can substitute these two values into the formula for the area of a triangle and simplify. Let's do it!

A=1/2bh

SubstituteII

b= 18, h= 7

A=1/2( 18)( 7)
