Width = 5x
length = 7x
Perimeter = 10x + 14x = 24x = 96cm
x = 96/24 = 4cm
width = 5x = 20cm
length = 7x = 28cm
Area = (20cm x 28cm) = 560 cm²
A ton is 2,000 so adding would take to long, so just multiply 2,000 and 40, and that will give you 80,000.
Answer:
1. In order for Pattern B to be linear, the common difference of the number of dots between each step should be constant. As it is not constant, the pattern is not linear.
2. In order for Pattern B to be exponential, the common ratio of the number of dots between each step should be constant. As it is not constant, the pattern is not exponential.
3. In order for Pattern B to be quadratic, its sequence of second differences must be constant.
First differences:

Second differences:

Therefore, as the sequence of second difference is constant, the patten is quadratic.
The function for pattern B is: 
(where x is the step number)
