A student incorrectly described the sequence of transformations that maps △DEF onto △D′E′F′ as a reflection across the x-axis, followed by a translation 6 units right and 4 units up. What mistake did the student likely make?

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
