FAST Cecilia made an envelope to mail a letter. She colored the regular trapezoid flap on the bottom of the envelope blue, as shown. A trapezoid has a base of 9 inches, height of 2 inches, and top side length of 5 inches. What is the area of the blue flap of the envelope? 14 Inches squared 18 Inches squared 45 Inches squared 90 Inches squared

The area is 14 inches squared.

Step-by-step explanation:

To find the area of a trapezoid the equation is...

a+b

x h                  (a and b equal the bases)

 2

Seeing as we know all of the basses and heights lets plug it into the equation.

9+5

x 2

  2

Well the 2 and the 2 cancel each other out in this scenario so what we would have to do now is ad 9 and 5 which would get us to 14.

the answer would be the last one (constat) she stays at the same rat every two mintues it goes up by 0.4
