Hi there!

The formula for an area A of a trapezoid with height h and bases of b1 and b2
A = h(b1+b2)/2

h= 12
b1 = 10
b2 = 15

A = 12(10+15)/2
= 6 * 25
= 150

The area is 150 ft².
Have an awesome day! :)

Select all the exspressions that are all equivalent to 20 percent of 150
Dmitriy789 [7]

<em>Note: It seems you may have unintentionally missed adding the answer choices. Thus, I am solving your question in general to give you the idea of how the percentage works, which anyways would solve your query.</em>

<em></em>

Answer:

Please check the explanation.

Step-by-step explanation:

Given that we have to determine the expressions which are equivalent to 20 percent of 150.

First, we need to determine what actually 20 percent of 150 really brings.

i.e

20% of 150 = 20/100 × 150

                   = 30

Thus,

20% of 150 = 30

Therefore, any expression that is equivalent to 30 will be included in the answer to this question.
