Exercise 34 Page 562

To find the area of a triangle, calculate one-half of the product of the base and the height.

9 yd^2

Practice makes perfect

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

In the given triangle, we can see that the base is 9 yards and that the height is 2 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

b= 9, h= 2

A=1/2( 9)( 2)

Evaluate right-hand side

Multiply

A=1/2(18)

1/b* a = a/b

A=18/2

Calculate quotient

A=9

The area of the triangle is 9 square yards.
