Answer 1

Answer:

length of rectangle=10.5 cm

width of rectangle=4.5 cm

Step-by-step explanation:

let the width of the rectangle be x cm. So, the length of the rectangle will be (x+6)cm

area of the rectangle would be (x^2+6x)cm^2

New width=x-3 cm

new length = x+3 cm

new area=(x^2-9)cm^2

according to the question,

x^2+6x=x^2-9 +36

6x=27

x=9/2 cm

x= 4.5 cm= width of rectangle

length of rectangle=10.5 cm
