Answer:
(6*3) - 5
Step-by-step explanation:
The product of 6 & 3 = 6*3 = 18
5 less than 18 means the required number is 5 units smaller than 18. so you have to subtract from 18
18 - 5 = 13
13 is 5 less than 18

Step-by-step explanation:
The error Alex made is that he found the perimeter of the figure instead of the area.
<h3>Area and perimeter of shapes</h3>
Given the expressions
7+(3x 1.4)+5+2+(5x 14)
He used the expression to simplify the grid
The expression simplified shows that Alex added all the measures of the sides of the grid instead of taking the product of the length and width
Note that the operation Alex performed is the perimeter of the figure instead of the area hence the error Alex made is that he found the perimeter of the figure instead of the area.
