Exercise 74 Page 15

Use the formula for finding the area of a triangle.

18 units^2

Practice makes perfect

We will use the formula for calculating the area of a triangle. A=1/2bh Now, we substitute the value of the base, b= 4, and the value of the height, h= 9, into the formula to calculate A.

A=bh/2

b= 4, h= 9

A=4( 9)/2

a/b=.a /2./.b /2.

A=2(9)/1

a/1=a

A=2(9)

Multiply

A=18

The area of the triangle is 18 squared units.
