Answer:

A=115.6

Step-by-step explanation:

Hey There!

So the first step is to find the formula for area of a trapezoid

A = \frac{1}{2} h(b1 +b2)

h = height

b1 = base 1

b2 = base 2

now all we do its plug in the values

A=\frac{1}{2} 6.8(28.3+5.7)

6.8x26.3=192.44\\5.7x6.8=38.76\\38.76+192.44=231.2\\\frac{231.2}{2} =115.6\\A=115.6

Hope this helps!!
