Because -7i and 7i are the solutions to the quadratic equation, you can first write it in factored form (x-7i)(x+7i). The you multiply this out and get x^{2} +49.
The leg would be the hypotenuse of the triangle on the ends of the trapezoid. The top base is 5 and bottom 11, the difference is 6 inches. This gives 3 inches on each side with a height of 4.
Use Pythagorean theorem to find the hypotenuse. 3^2+4*2=c^2
9+16=c^2
25=c^2
5.=c
The leg is 5 in
