Exercise 11 Page 295

To find the area, calculate half of the product of the base and the height.

6 cm^2

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 3 centimeters and that the height is 4 centimeters. 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= 3, h= 4

A=1/2( 3)( 4)
