Step-by-step explanation:
the property of a rectangle two opposite sides are the same. meaning the length that is X must have the same length on the other side right. Same thing as the side 2 4/5. so there are 2 of that same number. you're basically multiplying it by 2
expression
2x + 2(2 4/5) = P
if you don't understand that it's basically like this
x + x + 2 4/5 + 2 4/5 = P (it's the same as the above expression)
P = perimeter of rectangle
