I hope I helped a lot :D

& x = width of of pathway

then 2x + 2y = 90 > 2(x+y) =90 > x+y = 45 > perimeter of rectangle

x = 45-y

and xy = 350 > area of rectangle

( 45-y)(y) = 350

45y-y² -350 = 0 / . -1

y² - 45y +350 = 0

( y -10)(y-35) = 0

y = 10 or y = 35

so the length is 35m &

the width is 10m
