A NASA planetary probe survey a rectangular area of the Moon die young and determines the perimeter of the region to be 38 km if the length of the area is 2 km longer than the with what is the dimension

There appear to be some typos in this word problem; we assume this is a problem about a rectangle whose perimeter is 38km and whose length is 2km longer than its width... we further assume that we are to solve for the width and the length
let 'w' represent the width, then 'w+2' represents the length and we have this equation for perimeter:
2w + 2(w+2) = 38
solving for 'w' we have:
w = 17/2 = 8.5
8.5 + 2 = 10.5
the width is 8.5 km and the length is 10.5 km
