Answer: sara is 60
Step-by-step explanation: 64 divided by 4 equals 16. 16 plus 44 equals 60
I'd say the mode is probably also 12.
length of square = 18
x = side of square
x-7 = side of triangle
3(x-7) + 39 = 4x
3x-21 + 39 = 4x
3x+18 = 4x
18=x
square 18x4 =72(perimeter square)
triangle side (18-7=11)
11x3 = 33(perimeter triangle)
72-33=39
