X has to be inside the radical.
It would be
$\sqrt{ \frac{5x}{5} }$
Simplify the radical by breaking the radicand up into a product of known factors.

1. You have that:

- The trapezoids are similar.
- The larger base of the smaller trapezoid is 18 m and its area is 310 m².
- The larger base of the larger trapezoid is 32 m.

2. Then:

Sides=18/32
Sides=9/16

Area=(9/16)²
Area=81/256

3. Now, you can find the area of the larger trapezoid, as below:

81/256=310/x
81x=(310)(256)
x=79360/81
x=980 m²

Therefore, the answer is: The area of the larger trapezoid is 980 m².
