Step-by-step explanation:
The perimeter of any shape is the sum of the sides. A trapezoid has four sides, so the perimeter is found by adding the four side lengths together.
The trapezoid in this problem has side lengths of 5 mm, 2 mm, 5 mm, and 6 mm.
Add the sides together.
5 mm + 2 mm + 5 mm + 6 mm
7 mm + 5 mm + 6mm
12 mm + 6 mm
18 mm
The perimeter of the trapezoid is 18 millimeters.
The "bases" are the two sides of the trapezoid that are parallel.
