So the original lawn has an area
24 × 32 = 768 the new lawn will have area 425
this means the area of the sidewalk will be 768-425=343
now the sidewalk is a certain width of we draw it out and label it x we see the lawn has an area of

use the quadratic formula to solve. then you will know how wide the sidewalk is. I will attach picture
