Exercise 3 Page 292

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

110m^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 22 meters and that the height is 10 meters. 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= 22, h= 10

A=1/2( 22)( 10)

Evaluate right-hand side

Multiply

A=1/2(220)

1/b* a = a/b

A=220/2
