Exercise 7 Page 396

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

7 12 square yards

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 2 12 yards and that the height is 6 yards. 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= 2 12, h= 6

A=1/2( 2 12)( 6)
