Answer:
20 yd^2
Step-by-step explanation:
Your work is partially correct.
Assuming that the sides marked 8 yds and 2 yds are parallel, then the area of the trapezoid is
A = ( 8 yds + 2 yds)
------------------------ * 4 = 20 yd^2

When changing from radical form to fractional exponents, remember these basic forms:
The nth root of a can be written as a fractional exponent with a raised to the reciprocal of that power.
is taken, it’s raised to the 1/n power. When a power is raised to another power, you multiply the powers together, and so the m (otherwise written as m/1) and the 1/n are multiplied together.
Use fractions in the powers to indicate that the expression stands for a root or a radical.
Leave the exponent as 9/4. Don’t write it as a mixed number.
