They will have the same solution because the first equation of system b
is obtained by adding the first equation of system a to 4 times the
second equation of system a.
Please provide the table
Thanks,

I believe the answer is 9.7e-6
3^2 + height^2 = 9^2
9 + height^2 = 81
height ^2 = 72
height = sqrt(72)
Let the height of the rectangle = h
2b + 2h = 100
2(38) + 2h = 100
2h = 100 - 76
h = 12mm
area of rectangle = base x height
= 38 x 12
= 456mm²
