Answer:
280 students
111 non students
Step-by-step explanation:
number of students (S)
number of non students (N)
S+N=391 S=391-N
4S+6N=1786
substitute S
4(391-N)+6N=1786
1564-4N+6N=1786
subtract 1564 from each side
2N=222
N=111
S=391-111=280
So if the perimeters are equal then you know
Rectangle Triangle
x + x + x + 4 + x + 4 = x + x + 9 + x + 5
which becomes
4x + 8 = 3x + 14
now you can solve the equation for x, then find the perimeters
