The formula for finding the diagonals of any polygon is: 0.5*(n2-3n) where n = the number of sides. A trapezoid has 4 sides so: 0.5*(16-12) = 2 diagonals
The general formula to calculate area of a trapezoid ( and an isosceles trapezoid) is:AREA=(Sum of parallel sides)(Distance between parallel sides)/2. And if you find this formula difficult, calculate separately the area of two right angled triangles and a rectangles. For more details, contact at saqibahmad81@yahoo.com
There is no simple formula and, in any case, the answer will depend on what information about the trapezoid is given.

It depends on what x represents, and what information you have about the trapezoid.

Isosceles trapezoid ABCD has an area of 276 If AD = 13 inches and DE = 12 inches, find AB.

Area = 1/2*(sum of the 2 parallel sides)*height

Use a protractor and you'll find base angles are equal and that the 4 interior angles add up to 360 degrees
