Exercise 10 Page 377

Use the formula for area of a triangle.

154m^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=14m, and the value of the height, h=22m, into the formula to calculate A.

A=1/2bh

b= 14, h= 22

A=1/2( 14)( 22)

MoveRightFacToNumOne

1/b* a = a/b

A=14/2* 22

Calculate quotient

A=7* 22

Multiply

A=154

The area of the triangle is 154m^2.
