Step-by-step explanation:

let the width of the rectangle be x cm

then length of the rectangle =(x-2) cm

area of the rectangle= 120cm²

x(x-2)=120

x²-2x-120=0

x²-12x+10x-120=0

x(x-12)+10(x-12)=0

(x-12)(x+10)=0

x=12 or,x=-10

length can never be negative

therefore, x=12

length is 10cm

and width=12cm
