PQRS is a quadrilateral. The sides RS and QR are the same length. The sides QP and RS are parallel. Oh and also line SQ is 12cm and line QR is 9cm and is equal to line SR. Calculate: 1- angle SQR
2- angle PSQ
3- length PQ
4- length PS
5- the area of PQRS

Can any one me with the answers to these questions asap?
