Question 550995
let length be x
width be y

(x-5) new length
(y+2)  new width

Area = (x-5)(y+2)

Area = xy+2x-5y-10=260

in the square,  length = width = x

x^2+2x-5x-10=260
x^2-3x-270=0
x^2-18x+15x-270=0
x(x-18)+15(x-18)=0
(x-18)(x+15)=0
x= 18 the length of square

so rectangle width = 18-5=13mtr
length = 18+2=20 mtr
