Question

Find the area of quadrilateral one of whose diagonals is 40 cm square and the length of the perpendicular drawn from the opposite vertices on the diagonal are 16 cm and 12 cm

Answer 1

Answer:

Step-by-step explanation:

In quad.... ABCD

Diagnol bc divide it into two triangles ABC and DBC

area of ABC = 1/2x40x60

                     = 1200

area of DBC = 1/2x40x12

                     = 240

area of ABCD = 1200+240

                        = 1440
