Step-by-step explanation:
ABCD is quadrilater ,
ABC is a triangle , ADC is also a triangle .
find the area of quad.
given ,
AB = 3cm , BC = 4CM , CD = 4CM ,DA = 5CM and AC = 5 cm
# area of triangle ABC ,
= 1/2 . base . height
= 1/2 . 3 . 4
= 6cm .
# area of triangle ADC ,
= 1/2 . B . h
= 1/2 . 5 . 4
= 10 cm
area of quad. = area of triangle ABC + area of triangle ADC
= 6 cm + 10 cm
= 16 cm .
