Question

Abcd is a pralellogram ae is perpendicular to dc and cf is perpendicular to ad. If ab = 16 cm, ae =8cm and cf= 10 . Find ad

Answer 1

may be the answer is right

Answer 2

Answer:

Area of llgm ABCD with base DC = Area of llgm with base AD.

$\\ \sf \: DC \times AE = AD \times CF \\ \\ \\ \implies \sf \: 16 \times 8 = AD \times 10 \\ \\ \\ \implies \sf \: AD = \frac{16 \times 8}{10} \\ \\ \\ \implies \sf \blue{AD = 12.8 \: cm}$
