Make the drawing and everything will fall into place. You said, "isosceles trapezoid". You have a rectangle central part, and two 45-45-90 triangles each at left and right sides. The height of 7 units means that each bottom leg of a triangle is also 7 units. The entire bottom base is therefore units.
