Answer 1

use formulae a=lb
l=4b
A=4b×b

Answer 2

let the breadth of the rectangle be X

then the length of the rectangle is four times breadth  i.e. 4X

area of rectangle = length*breadth

                             = 4X*X

                             =4X^2

so 4X^2 is the equation in which you can put the value of length or breadth to find its area.
