➷ Use this formula:
Area = ((a + b)/2) x h
a is the top length
b is the bottom length
h is the vertical height
1) Substitute in the values:
((3.8 + 6.2)/2) x 7 = 35ft^2 <== this is the answer
2) Substitute in the values:
((10.3 + 15.1)/2) x 12.6 = 160.02in^2 <== this is the answer

We are given with the formula
p = 200k - 500
a) The constraint for this formula is obtained from the idea that the profit must be positive
200k - 500 > 0
k > 500/200
k > 2.5
b) To make 14000 profit
14000 = 200k - 500
k = 72.5 or 73 knives must be sold
