ar. of square = 64sq. m
let length = x
therefore breadth = 2/5x
area of rect. = x*2/5x
A/Q- ar of square-4= 2/3*x*2/5x
64-4=2/3*x*2/5x
60=4/15x^2
x^2=60×15/4=225
x=15m= length
x2/5=15*2/5=6m=breadth
let length = x
therefore breadth = 2/5x
area of rect. = x*2/5x
A/Q- ar of square-4= 2/3*x*2/5x
64-4=2/3*x*2/5x
60=4/15x^2
x^2=60×15/4=225
x=15m= length
x2/5=15*2/5=6m=breadth

Answer:
6 meter = breadth;
15 meter = length.
Step-by-step explanation:
area of square = 64sq. m
let length = x
therefore breadth = 2/5x
area of rect. = x*2/5x
A/Q- ar of square-4= 2/3*x*2/5x
64-4=2/3*x*2/5x
60=4/15x^2
x^2=60×15/4=225
x=15m= length
x2/5=15*2/5=6m=breadth
