Question 1173500
<br>
Picture dividing the trapezoid into a rectangle and two 30-60-90 right triangles.<br>
In each of the 30-60-90 right triangles, the hypotenuse is 12, so the base is 6 and the height is 6*sqrt(3).<br>
With the base of each triangle being 6, the width of the rectangle is 25-2(6)=13.<br>
Each diagonal of the trapezoid is then the hypotenuse of a right triangle with legs 13+6=19 and 6*sqrt(3).<br>
Use the Pythagorean Theorem to calculate the length of each diagonal.<br>
Then multiply the total length of the two diagonals by the given cost per foot and round the answer to the nearest dollar, as instructed.<br>
