Answer 1

Answer:

Step-by-step explanation:

ERE IS YOUR ANSWER. ..

Area of Quadrilateral = Area of triangle 1 . + Area of triangle 2 .

Area of triangle 1 . = whole root 21 (21-15)(21-13)(21-14)

= whole root 21 (6)(8)(7)

=whole root 7056

=84

Area of triangle 2. = whole root 18 (18-15)(18-9)(18-12)

= whole root 18 (6)(3)(9)

=whole root 2916

= 54

Area of Quadrilateral = 54 + 84

= 138 Ans ....
