sorry

Step-by-step explanation:

I don't know the answer

Answer 2

Step-by-step explanation:

in triangle ABC,

b=√5²-3²

b =√25-9

b=√16

b=4

in triangle BCD,

b=√5²-4²

b=√25-16

b=√9

b=3

area of triangle ABC,

1/2×4×3

=6

area of triangle BCD,

1/2×4×3

=6

area of ABC+ BCD=ABCD

6+6=12

SO,area of quadrilateral ABCD is 12cm.
