Step-by-step explanation:

area of polygon= area of triangle +area of rectangle

area of triangle=1/2×18×13

=9×12

=108 cm^2

area of rectangle=18×13

=234cm^2

=108+234

=342cm^2

Answer 2

Answer:

area of this fig= area of rectangle+ area of triangle

area of rectangle= 13×18= 234sq cm

area of triangle = 1/2× 18×(25-13)

= 1/2× 18× 12

= 9×12

= 108sq cm

Area of fig= 234+ 108

= 342sq cm
