Please tell me answer of this question with step by step explanation



find the area of quadrilateral ABCD from the given measurements in the following
​

Answer 1

Area of the quadilateral ABCD = Area of the triangleABC + Area of the right angle triangle AED + Area of the triangle AEC

Dimensions of the triangle AEC:

AE =6 cm

EC = 21 cm

= 1/2 × b × h

= 1/2 ×21 × 6

=63 cm sq.

Similarly,

Area of the Triangle ABC = 1/2 ×15 ×8

=60 cm sq.

Area of the triangle AED = 1/2 × 6×6

=18 cm sq.

Area of quadrilateral =141 cm sq.
