Exercise 4 Page 396

Use the formula for the area of a triangle.

4ft^2

Practice makes perfect

Let's take a look at the given triangle.

Remember the formula for the area of a triangle. A=1/2bh In this formula, b is the length of the base and h is the height. For our triangle, we will substitute b= 4 feet for the base and h= 2 feet for the height into the formula to calculate A. Let's do this!

A=1/2bh

b= 4, h= 2

A=1/2( 4)( 2)

MoveRightFacToNumOne

1/b* a = a/b

A=4/2* 2

FracMultDenomToNumber

a/2* 2 = a

A=4

The area of the triangle is 4 square feet.
