Question

The diagonals of a quadrilateral are 16 cm and 13 cm. If they intersect each other at right angles; find the area of the quadrilateral.

Sum

Solution

Area of the quadrilateral = `1/2 ` x the product of the diagonals.
                                        = `1/2 xx 16 xx 13`
                                        = 104 cm
