Will give brainliest. if the area of a parallelogram is to remain constant, what change must take place in the base if the altitude is multiplied by three? ( by(1b) if the altitude is divided by two? ( by(2b) 1a) a. divide. b. multiply. c. addition. 1b) a.6 b.3 2a) a. divide. b. multiply 2b) a. 2 b. 6 , will give brainliest.

The answers are:

1a --> divide

1b --> 3

2a --> multiply

2b --> 2

By the way, I turned in my assignment and these are the answers on the answer key, so they are correct for sure!   :)

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
