Final answer:
If trapezoid ABCD has a perimeter of 48m, then trapezoid EFGH would also have a perimeter of 48m.
Step-by-step explanation:
A trapezoid, also known as a trapezium in some regions, is a quadrilateral (a polygon with four sides) with at least one pair of parallel sides. The parallel sides are called the bases, and the non-parallel sides are the legs. The legs may have different lengths, and the angles between the bases and each leg may also vary.
Trapezoids ABCD and EFGH are congruent, which means they have the same shape and size. When two trapezoids are congruent, their corresponding sides and angles are equal. So, if trapezoid ABCD has a perimeter of 48m, then trapezoid EFGH would also have a perimeter of 48m.
