# A plot is in a shape of a quadilateral ABCD in which side AB = 18cm , AD= 24cm, BC =40cm,DC= 50cm then find the area of the plot?

Try constructing it in the easiest way possible. Here's one, first construct AB & AD perpendicular to each other (this is right-angled triangle at A with BD=30).

Now, you have BC=40, CD=50 & diagonal BD=30 (observe ∆BCD is right-angled at angle DBC).

Two right triangles BAD & DBC, their corresponding areas are ½(18)(24) and ½(30)(40).

Area of quadrilateral is (216)+(600) = 816.
