Exercise 3 Page 338

To find the area calculate, one half the product of the height and the sum of the bases.

4cm^2

Let's find the area of the given trapezoid. The area of a trapezoid is one half the product of the height and the sum of the bases.

In the given trapezoid we can see, that the height is 2 centimeters and the bases are 2.4 centimeters and 1.6 centimeters. We can substitute them into the formula for the area of a trapezoid. Let's do it!

A=1/2h(b_1+b_2)

SubstituteValues

Substitute values

A=1/2 2* ( 1.6+ 2.4)

▼

Evaluate right-hand side

Add terms

A=1/22* (4)

Multiply

A=1/2* 8

MoveRightFacToNumOne

1/b* a = a/b

A=8/2

Calculate quotient

A=4

The area of the trapezoid is 4 square centimeters.
