The area of the rectangle is length times width, that is
A = L*W
The problem requires the width so
W = A/L
Given that A = 437 sq. cm and L = 19 cm, therefore
W = 437/19 = 23 cm
That is the answer.

Step-by-step explanation:
add all of them up, Julie, 6 + 12 + 3 + 4 = 25
there are 25 total students. now divide each of the number of people that speak that language by the total students
6/25 = .24 = 24%
12/25= .45 = 48%
3/25 = .12 = 12%
4/25 = .16 = 16%
Also, if you want to just check, see if the percentages add to 100%
Distribute on the left side
7.4a+22.2=3.2a+43.2
Subtract 3.2a from both sides
4.2a+22.2=43.2
Subtract 22.2 from both sides
4.2a=21
Divide both sides by 4.2
a=5
7<n<8 is the right answer
