    3+3+3=9=1 triangle
    4+4+2+2=12=1 rectangle
    3+3+3+3=12=1 square
    9x10=90 for 10 squares
    8x12=96 for 8 rectangle
    4x12=48 for 4 squares
    90cm+96cm+48cm=234cm for total perimeter

    perimeter of triangle=s^3=s+s+s
    perimeter of square= l+l+w+w
    perimeter of square=s^4=s+s+s+s
