Answer 2

Answer:

length=17, breadth =8

Step-by-step explanation:

let breadth =x

length =x+9

so area of initial rectangle is x square+ 9x

the other rectangle's dimensions are x+3 and x+12

given that 2nd rectangle is 84+ first rectangle

(12+x)(3+x)=84+ x square + 9x

x square+ 15x+36= 84+ x square+ 9x

15x-9x=84-36

6x=6(14-6)

x=8

so breadth is 8. length is 17
