Question

Two sides of a quadrlateral are 64 cm and 48 cm in
length and the angle between them is 90°. The other
two sides are 50 cm each. The other three angles of
the quadrilateral are nor right angles. What is the area
of the quadrilateral?​

Answer 1

Answer:

990

Step-by-step explanation:

ABC is right angled,

therefore area of ABC = 48 x 64 / 2 cm sq

                                    = 1532 cm sq

In triangle ADC,

AC =

    = 80 cm

s = (50 + 50 + 80)/2 cm

 = 90 cm

Area of ADC =  cm sq

                    =  cm sq

                    =  cm sq

                    = 900 cm sq

Total area = area of ABC + area of ADC

                = (900 + 90) cm sq

               = 990 cm sq
