Sarah's rectangular garden has a perimeter of 3 27 + 3 27 + 258 + 218 cm

What is the perimeter of the rectangle in simplest form?

Alright, so basically the permiter that is given is like this:

327+327 + 258+258 cm = 1170cm

now this can also be written as: 2 (327+258) cm = 1170cm

wait, its given as 258 and 218 cm. the width should be same actually, then only you can simplify it in order to get it in an expression (simplest form)

Sarah's perimeter is 1130
