Final answer:
The perimeter of quadrilateral PQRS is 33.0 units (nearest tenth).
Step-by-step explanation:
To find the perimeter of a quadrilateral, we need to add up the lengths of all four sides. Let's assume the lengths of the sides of the quadrilateral PQRS are given as follows:
PQ = 10 units
QR = 8 units
RS = 6 units
PS = 9 units
Adding up the lengths of all four sides, we get:
Perimeter = PQ + QR + RS + PS = 10 + 8 + 6 + 9 = 33 units
So, the perimeter of quadrilateral PQRS is 33.0 units (nearest tenth).
