Question

In the given figure, PQRS is a parallelogram. If perimeter of parallelogram PQRS is 40 cm and $PQ=12cm$, then PS is equal to

• A. $12cm$
• B. $10cm$
• C. $8cm$
• D. $9cm$

Answer 1

The correct option is C $8cm$

Perimeter of $\parallel gm$ $=40cm$

$2(PQ+PS)=40cm$

$2(12+PS)=40$

$PS=\left(40/2\right)-12$

$PS=8cm$
