Step-by-step explanation:
Area of triangle =21× base × height
For base QR=10cm, height PM=4.4cm.
So, area =21×10×4.4=22cm2
Let the altitude QN for base PR=11cm, be h.
Area of the triangle will be the same considering any side of the base and its corresponding height.
Hence, area =21×11×h=22cm2=>h=4cm
