1. pre - unit

what is the area of the rectangle? explain or show your reasoning.

Explanation:

Step1: Calculate water in 6 bottles

To find the total water in 6 bottles, multiply the amount of water in one - bottle by 6. One bottle holds $\frac{7}{10}$ liter of water. So the calculation is $6\times\frac{7}{10}$.
$6\times\frac{7}{10}=\frac{6\times7}{10}=\frac{42}{10} = 4.2$ liters.

Step2: Calculate area of rectangle

The formula for the area of a rectangle is $A = l\times w$, where $l$ is the length and $w$ is the width. Here, $l = 12$ cm and $w = 8$ cm.
$A=12\times8 = 96$ $cm^{2}$

Answer:

6 bottles hold 4.2 liters of water. The area of the rectangle is 96 $cm^{2}$.
