A- price of adult's ticket
c- price of children's ticket
a+3c=20
a=c+2
c=a-2
a+3(a-2)=20
a+3a-6=20
4a=26
a=6.5

Answer:
1232 m^2.
Step-by-step explanation:
The net consists of 2 triangles and 3 rectangles.
Area of each triangle = 1/2 * 24*7 .
Area of 1 rectangle = 25 * 19.
The other 2 have areas 24*19 and 7 * 19.
Therefore the surface area of the prism
= 2 * 1/2 * 24 * 7 + 25*19 + 24*19 + 7*19
= 1232 m^2.
