Step-by-step explanation:
the width of path same
find area of inside rectangle
we get
20*14=280
next find length width of big rectangle
length of inside is 20 outer rectangle is x+x+20=20+2x
same as width is 14+2x
now find area of outer
(20+2x)*(14+2x)
now using area of path 111
area of outer rectangle-inside rectangle
(20+2x)*(14+2x)-280=111
4x²+68x-111=0
now simplyfy quadratic form we get answers
