The mistake is in step 3:
I: −2m =−12 − 2n
II: 2m = 8 + 8n
the student set both right sides of the equations equal (−12 − 2n = 8 + 8n), but the left sides aren't equal: first equation has -2m, second has +2m so the signs of one of the equations must be inverted first
The area of the rectangle would be 44 this is because area is Length x Width so the very top of the rectangle is 4 cm and going up on the side is 11 so 4x11 is 44 which is ur area.
Hope this helps!
