X=-2, x=2, and x=3 these are the critical points
Let 's x the width of the sidewalk.
Area of the swimming pool= 10*16=160 (ft²)
Area of the sideway+the swimming pool= (16+2x)*(10+2x) =160+155
==>160+20x+32x+4x²=160+155
==>4x²+52x-155=0
Δ=52²+4*4*155=5184=72²
==>x=(-52+72)/2=5/2 or x=a negative to exclude.
Width of the sideway=5/2 ft
so tell me if i helped
