Exercise 24 Page 638

We want to find the area of the triangle with a base of 52 feet and a height of 38 feet. We can use the following formula to do it. A=1/2 b h In this formula, b is the length of the base and h is the height. For our triangle, we will substitute b= 52 for the base and h= 38 for the height into the formula to calculate A.

A=1/2bh

SubstituteII

b= 52, h= 38

A=1/2( 52)( 38)

MoveRightFacToNumOne

1/b* a = a/b

A=52/2(38)
