BD is one of the diagonals of a quad. ABCD. If `ALbotBD and CMbotBD`, show that
`ar("quad. ABCD")=(1)/(2)xxBDxx(AL + CM)`.

Calculate the area of quad. ABCD.

If the length of diagonal BD of a square ABCD is 4.8 cm, the area of the square ABCD is :

The diagonals of quad. ABCD cut at right angle then find AB^(2)+CD^(2) = ?

In a quad. ABCD it is given that BD = 16 cm. If AL bot BD and CM bot BD such that AL = 9 cm and CM = 7 cm, then ar(quad. ABCD) = ?

In a quadrilateral ABCD, it is given that BD = 16 cm. If AL bot BD and CM bot BD such that AL = 9 cm and CM = 7 cm then ar(quad. ABCD) = ?

ABCD is a quadrilateral in which diagonal BD = 64 cm. AL bot BD" and "CM bot BD , such that AL=13.2cm" and "CM=16.8cm . The area of the quadrilateral ABCD is square centimeters is :

If AC and BD are diagonals of a parellelogram ABCD, show that

In the given figure ABCD is a quadrilateral in which diagonal BD=24 cm, AL bot BD and CM bot BD such that AL=9 cm and CM=12 cm. Calculate the area of the quadrilateral .
