Question

In given figure ABCD is a quadrilateral in which AC =14cm BL is perpendicular to AC, DMis perpendicular to AC such that BL = 8cm ,DM = 6cm .find the area .

Answer 1

area of quadilatral ABCD = Area of triangleDAC +Area of triangle BAC

Area of quadilatral ABCD= 1/2 ×DM×AC + 1/2 × BL × AC

Area = 1/2 × 6 × 14 + 1/2 × 8 × 14

Area of quadilatral ABCD =( 42 +56 )cm square
Area of quadilatral ABCD = 98 cm square
