Answer:
let's begin.
Step-by-step explanation:
BCD triangle's
base = 16 cm
height = 10 cm
area of BCD triangle = 1/2×16×10 square cm
= 80 square cm
ABD triangle's
base = 16 cm
height = 6 cm
area of ABD triangle = 1/2×16×6 square cm
= 48 square cm
total area of ABCD quadrilateral=ABD triangle's area+BCD triangle's area
=(48 +80) square cm
=128 square cm
