Question
Here is an area diagram that represents (3.1) $\cdot$ (1.4).a. Find the areas of sub-rectangles A and B.b. What is the area of the $3.1$ by $1.4$ rectangle?
Step 1
The area of a rectangle is given by the product of its length and width. Here, the length is 3.1 and the width is 1. So, the area of A is $3.1 \times 1 = 3.1$. Show more…
