Question

in a parallelogram ABCD it is being given that Ab=10 cm and the altitudes corresponding to the sides AB and AD are DL=6cm and BM= 8cm,respectively.find AD

Answer 1

Using the formula of area of parallelogram,
$base1 \times altitude1 = base2 \times altitude2 \\ 6 \times 10 = 8 \times ad \\ ad = \frac{60}{8} = \frac{15}{2} = 7.5cm$
