The error Alex made while simplifying the expression 7+(3x 1. 4)+5+2+(5x1. 4) is "he found the perimeter of the figure instead of the area".
<h3>How to find area of an object?</h3>
The area of an object is the product of the length and width of the objects.
Alex added the dimensions of the grid instead of multiplying them.
7+(3x 1. 4)+5+2+(5x1. 4)
For instance,
- Area of a rectangle = length × width
- Perimeter of a rectangle = 2(length + width)
Therefore, Alex found the perimeter of the figure instead of the area".

Can you provide a screenshot? I could help you better with a visual.
Answer:
The correct option is commutative property.
Step-by-step explanation:
The expression that Renee is simplifying is:
It is provided that, Renee recognizes that 7 and 
are reciprocals, so she would like to find their product before she multiplies by 
.
The associative property of multiplication states that:
The commutative property of multiplication states that:
The distributive property of multiplication states that:
The identity property of multiplication states that:
So, Renee should use the commutative property of multiplication to find the product of 7 and ,
Thus, the correct option is commutative property.
