Question

Or
What is the area of the trapezoid?

Answer 1

54 square centimeters

Explanation:

The question asks us to calculate the area of the trapezoid. To do this, we need to use the following formula:

`\boxed{A = (1)/(2)(a + b) * h}`,

where:

A ⇒ area of the trapezoid

a, b ⇒ lengths of the two parallel sides = 3 cm, 9 cm

h ⇒ perpendicular height of the trapezoid = 9 cm

Using the above formula and information, we can calculate the area:

A =
`(1)/(2) * (3+9) * 9`

=
`(1)/(2) * 12 * 9`

=
`\bf 54`

Therefore, the area of the trapezoid is 54 cm².
