Answer:
[tex]34y-14[/tex]
Step-by-step explanation:
A rectangle has 4 sides.
The perimeter is the sum of all 4 sides.
We have 2 lengths and 2 widths.
Since 10y + 2 is length & 7y - 9 is width, the perimeter will be:
Perimeter = [tex]Length + Length + Width + Width = 10y+2+10y+2+7y-9+7y-9[/tex]
We combine the like terms (y terms) and the numbers and simplify the expression to be:
Perimeter = [tex]10y+2+10y+2+7y-9+7y-9=34y-14[/tex]
The perimter = 34y - 14
