Question

an ice - cream shop serves about 60 customers in one day. about how many customers does the ice - cream shop serve in 40 days? which rectangle represents the problem? each square is 10 units wide and 10 units long.

Explanation:

Step1: Calculate total customers in 40 days

Multiply daily customers by days. $60\times40 = 2400$.

Step2: Analyze area of rectangles

Each square has area $10\times10=100$. Count squares in rectangles to find area.
The first rectangle has $4\times6 = 24$ squares, area is $24\times100 = 2400$.
The second rectangle has $4\times5=20$ squares, area is $20\times100 = 2000$.
The third rectangle has $6\times6 = 36$ squares, area is $36\times100=3600$.

Answer:

The first rectangle represents the problem.
