Answer:

12

Step by step explaination:

Since PQRS is an isosceles trapezoid, two of its sides are equal. We can assume that QR and PS is the pair of congruent sides because of the ordering and naming of the whole trapezoid. That means that you just add 2 for the last side, PS, to the sum of all the other sides, giving you a total of 12. (2+3+5=10, 10+2=12)

Answer:

12 cm.

Step-by-step explanation:

I drew the trapezoid in the picture. As the trapezoid is isosceles we assume that the sides marked has the same length. So, the perimeter is

P= 5 cm+ 2 cm + 3 cm + 2 cm = 12 cm.
