Answer: 243 sq cm.Step-by-step explanation: Given Find the area of the quadrilateral ABCD in which AB=9cm , BC=40cm , CD=28cm, DA =15cm and ∆ABC = 90° ...
Answer: 243 sq cm.Step-by-step explanation: Given Find the area of the quadrilateral ABCD in which AB=9cm , BC=40cm , CD=28cm, DA =15cm and ∆ABC = 90° ...So AC = 41 cm. Now area of triangle = 1/2 x b x h.
Answer: 243 sq cm.Step-by-step explanation: Given Find the area of the quadrilateral ABCD in which AB=9cm , BC=40cm , CD=28cm, DA =15cm and ∆ABC = 90° ...So AC = 41 cm. Now area of triangle = 1/2 x b x h.= 1/2 x 9 x 40 = 180 sq cm. Now to find the other side of triangle using heron's formula we get.
