12 cm7.6 cmPQRS is a parallelogram. PM is theheight from P to SR and PN is theheight from P to QR. IFSR = 12 cmand PM= 7.6 cm.Š Find the area of the paral-lelogram PQRS 902 Find PN, if QR=8 cm. |

Answer» PQRS is a parallelogram, we know,area = b* h = SR * PM here SR = 12cm , PM = 7.6 cm so, area of PQRS = 12cm * 7.6 cm = 91.2 cm² 2). area = SR * PM = QR * PN so, 91.2 cm² = 8cm * PN 91.2/8 = PN PN = 11.4 cm hence, PN = 11.4 cm |
