Exercise 2 Page 302

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

26 km^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 8 kilometers and that the height is 6.5 kilometers. 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= 8, h= 6.5

A=1/2( 8)( 6.5)

Evaluate right-hand side

Multiply

A=1/2(52)

MoveRightFacToNumOne

1/b* a = a/b

A=52/2

Calculate quotient

A=26

The area of the triangle is 26 square kilometers.
