The perimeter of a parallelogram can be calculated using the formula: Perimeter = 2 × (length + width).
In parallelogram PQRS, we can identify the lengths of sides SR and QR. Given that SR measures 42 units (as it is opposite to PQ), and QR measures 10 units (as it is opposite to PS), we can substitute these values into the formula.
So, the calculation for the perimeter is:
- Length (SR) = 42
- Width (QR) = 10
Now plug in the values:
Perimeter = 2 × (42 + 10) = 2 × 52 = 104 units.
Therefore, the perimeter of parallelogram PQRS is 104 units.
