Exercise 5 Page 396

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

56 square millimeters

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 14 millimeters and that the height is 8 millimeters. 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= 14, h= 8

A=1/2( 14)( 8)

Evaluate right-hand side

Multiply

A=1/2(112)

MoveRightFacToNumOne

1/b* a = a/b

A=112/2

Calculate quotient

A=56

The area of the triangle is 56 square millimeters.
