The perimeter of a rectangle is 53 meters. the length is 2.3 meters longer than the width, w. write and solve and equation to find the width of the rectangle.

Perimeter = 2*(length + width)
53 m = 2*(2.3 m +w) . . . . an equation to find the width, w
26.5 m = 2.3 m +w . . . . . divide by 2
24.2 m = w . . . . . . . . . . . subtract 2.3 m

The width of the rectangle is 24.2 m
