Answer:
a. 16 sq cm
b.20 sq cm
Step-by-step explanation:
Area of a parallelogram:
A = b•h
A = 4•4 = 16 sq cm
Area of a trapezoid:
A = 1/2(b+b)•h
A = 1/2(6+4)•4
A = 1/2(10)•4
A = 20 sq cm
The system of equations would be:
64x+132y = 1040
x = 2y
We multiply the number of adult tickets, 64, by the cost of the adult tickets, x. We multiply the number of student tickets, 132, by the cost of the student tickets, y. Together these add up to $1040.
We know that the cost of an adult ticket is twice as much as a student ticket, so x = 2y.
