Find the perimeter in feet of trapezoid ABCD with AB ≅ DC.

Question

Find the perimeter in feet of trapezoid ABCD with AB ≅ DC.

6 ft

4 ft

12 ft

Trapezoid A B C D contains four labeled vertices and a dashed line segment.

1. The left side starts at vertex A, goes down and to the left and ends at vertex B.
2. The bottom side is horizontal, starts at vertex B on the left and ends at vertex C on the right. It is labeled 12 ft.
3. The right side starts at vertex C, goes up and to the left and ends at vertex D.
4. The top side is horizontal, starts at vertex D on the right and ends at vertex A on the left. It is labeled 6 ft.
5. A dashed line segment goes down vertically from vertex A and meets side B C at a right angle. It is labeled 4 ft.

Answer 1

AD + DC + BC + BA = 6 + 6 + 12 + 6 = 30
