let width of path be x
sides of iner rectangle will be (54-2x) and (35-2x)
area of rectangular field -area of iner rectangle = area of path
54x35 - [(54-2x)(35-2x)]=420
Now solve for x
x is the width of path
sides of iner rectangle will be (54-2x) and (35-2x)
area of rectangular field -area of iner rectangle = area of path
54x35 - [(54-2x)(35-2x)]=420
Now solve for x
x is the width of path
