Respuesta :

The area of a trapezoid is:

[tex]A = \frac{a + b}{2} h[/tex]

A = area

a = base 1

b = base 2

h = height

Area = unknown

base 1 = 2.5

base 2 = 7.5

height = 2.5

^^^Plug these numbers into the formula!

[tex]A = (\frac{2.5 + 7.5}{2} )(2.5)[/tex]

A = (10/2)(2.5)

A = (5)(2.5)

A = 12.5

Hope this helped!
