Answer:
You can solve by the formula of area of trapezium. This is h(a+b)/2.
54 = 6(8+b)/2
Thus b = 10cm.
Since these are similar triangles you can use any two corresponding sides to figure out the scale factor.
Use the bottom side. Going from the first triangle to the second the scale factor is:
15/9 = 5/3
Your graph is correct.
You start with point (0, 40). On day 0, you have 40 T-shirts.
Each day that passes, you have 5 shirts fewer. (1, 35) means on day 1, you have 35 shirts left. Each day that passes, there are 5 fewer shirts. On the 8th day, there are no shirts left. That is point (8, 0).
Good job!
