A rectangle has a length of 40 meters and a width of 20 meters. A similar smaller rectangle has half the length and width of the big rectangle. What's the area of the smaller rectangle? Give the rationale and then the answer.
Let's think step by step. The length of the smaller rectangle is 1 / 2 * 40 = 20 meters. The width of the smaller rectangle is 1 / 2 * 20 = 10 meters. Since the area of a rectangle is found by multiplying the length times the width, the total area of the smaller rectangle is 20 * 10 = 200 meters square.. The answer is: 200.

Jerry is writing a script for a skit with three characters. The first character has eight more lines than the second character. The third character only has two lines. The second character has six more than three times the number of lines the third character has. How many lines does the first character in Jerry’s skit script have? Give the rationale and then the answer.
Let's think step by step. The second character has 6 + 3 * 2 = 6 + 6 = 12 lines. The first character has 12 + 8 = 20 lines.. The answer is: 20.

Sam has 18 cows. 5 more than half the cows are black. How many cows are not black? Give the rationale and then the answer.
