Explanation:

Cindy's Gift Problem

Step1: Calculate annual gifts

Cindy gets \( 5 + 6 + 4 = 15 \) gifts per year.

Step2: Calculate total for 6 years

Multiply annual gifts by 6: \( 15\times6 = 90 \).

Step1: Calculate total baked cookies

Henry bakes \( 4\times12 = 48 \) cookies.

Step2: Subtract eaten cookies

Subtract 5 from total: \( 48 - 5 = 43 \).

Step1: Recall area formula

Area of a rectangle: \( A = l\times w \), where \( A = 6 \) sq ft.

Step2: Find length and width

Possible pairs: \( l = 6 \) ft, \( w = 1 \) ft; \( l = 3 \) ft, \( w = 2 \) ft (any pair with product 6).

Answer:

90
