Answer:
the lenght of CD is 6
Step-by-step explanation:
BC =6 and DB=9 substract DB with BC (9-6=3) it increases by 3 so thats why from BC is 6 and from B to D is 9 bc it increased by 3
(7/2) m is the width and 18m is the length. This is because area is lxw.let w= width and length=11+2wMultiply together, get 2w^2+11w-63=0factor to get (2w-7)(w+9).Find w and get w=7/2 and w=-9Negative rejected because a measurement can't be negative. Finally substitute that into the length equation (11+2w) to get 18m and width is 7/2 m
