Answer: Space was alloted for each subject is 8 dm, 8 dm, 12 dm.

Explanation:

Since we have given the length of bulletin board =28 dm

Let the share of three subject areas be 2x,2x,3x

According to question,

$2x+2x+3x=28\\7x=28\\x=\frac{28}{7}\\x=4dm$

so x=4 dm

Now,

Space was alloted for each subject is given as below:

First subject = $2x=2\times 4=8 dm$

Second subject = $2x=2\times 4=8 dm$

Third subject = $3x=3\times 4=12 dm$
