Question

The area of a quadrilateral whose diagonal is 12 cm and the lengths of the perpendiculars drawn from the vertices on the diagonal are 5cm and 15 cm

Answer 1

Answer:

area of parallelogram =30+90=120cm^2

Step-by-step explanation:

the diagonal divides the quadrilateral into two triangles

area(2triangles )=area of paralellogram

1st triangle=h x b x 1/2

                 =5 x 12 x 1/2

                 =60/2

                 =30cm^2

2nd triangle=h x b x 1/2

                   =15 x 12 x 1/2

                   =180/2

                   =90cm^2
