Construct a parallelogram ABCD in which AB=6.5cm AC=3.4cm and the altitude AL from A is 2.5cm. Draw the atitude from C and measure it
Given a parallelogram with AB = 6.5 cm, AC = 3.4 cm and perpendicular from point A on CD is AL = 2.5 cm.
The length of perpendicular on AB from point C = AL = 2.5 cm.
This is because AB and CD are two parallel sides and distance between parallel sides is equal.
Hence, the length will be 2.5 cm
