Exercise 44 Page 608

Use the formula for the area of a triangle.

58.5 in.^2

Practice makes perfect

Here we will use the formula for calculating the area of a triangle. A=1/2bh Now we substitute the value of the base, b= 13, and the value of the height, h= 9, into the formula to calculate A.

A=1/2bh

SubstituteII

b= 13, h= 9

A=1/2( 13)( 9)

MoveRightFacToNum

a/c* b = a* b/c

A=13/2* 9

CalcQuot

Calculate quotient

A=6.5*9

Multiply

A=58.5
