Answer:
18.7 cm²
Step-by-step explanation:
To work out the area of a triangle you have to use the formula

Where "B" is the base and "H" is the height
Since these are decimals, I like to convert them into fractions which makes them easier to calculate with
The base is 4.25 cm which will turn into 
The height is 8.8 cm which will turn into 
Now we use the formula


→ Convert to improper fractions

→ Simplify

→ Convert into decimal
18.7

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.
