b + (2b+9) = 60
3b = 51 . . . . . . . . . subtract 9
b = 17 . . . . . . . . . . divide by 3
Betty has $17 and Ann has the other $43 of the total of $60.

A "regular quadrilateral" is a square, so the length and width are both 4 cm. The surface area of a rectangular prism is given by
S = 2(LW +H(L +W))
S = 2((4 cm)*(4 cm) +(6 cm)*(4 cm +4 cm))
S = 2(16 cm² +48 cm²)
S = 2*64 cm² = 128 cm²
The surface area of the prism is 128 cm².
Yes it is greater than 1/2
