Question

Area of a quadrilateral ABCD is 20 cm² and perpendicular on BD from opposite vertices are 1 cm and 1.5 cm. Find the length of BD.

Please answer it fast.​

Answer 1

Area of Quadrilateral = 20 cm².

Vertices are 1 cm and 1.5 cm.

Then,

Area of quadrilateral = (1/2) * (1 + 1.5) * BD

=> 20 = (1/2) * (2.5) * BD

=> 40 = 2.5 * BD

=> BD = 16 cm

Hence, length of BD is 16 cm.
