Exercise 4 Page 534

Use the formula for area of a triangle.

10cm^2

Consider the given diagram of the triangle.

We can find the area of a triangle. We will use the following formula to do it. 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= 5 for the base and h= 4 for the height into the formula to calculate A.

A=1/2bh

b= 5, h= 4

A=1/2( 5)( 4)

Multiply

A = 1/2(20)

MoveRightFacToNumOne

1/b* a = a/b

A = 20/2

Calculate quotient

A = 10

The area of the triangle is 10cm^2.
