Set up the equations:
2x+3y=80
1x + 4y = 100
solve for x and y:
1x + 4y = 100
x = 100-4y
plug into first equation
2(100-4y)+3y=80
200-8y+3y=80
y=120/5=24
x = 100-4y=100-96=4
So the charges are (x,y)=(4,24)
So the correct answer (B)

Step-by-step explanation:
We know that to find the perimeter you have to add all sides (the dimensions) so that would be width plus height plus width plus height.
P = w + h + w + h
Since we're only given the measurements of the perimeter, to find the dimensions we have to divide the perimeter by 4 since there are 4 sides.
228 = 4s (sides)
228/4 = s
57 = s
