THERE ARE MANY ANSWERS TO THIS QUESTION.
X^2+Y^2=36
IF X IS THE LENGTH OF 4 THEN:
16+Y^2=36
Y^2=36-16
Y^2=36-16
Y^2=20
Y=SQRT20
Y=4.47 FOR THE WIDTH
PROOF
4*2+4.4762=36
16+20=36
36=36
ALSO IF X IS THE LENGTH OF 5 THEN:
5^2+Y^2=36
25+Y^2=36
Y^2=36-25
Y^2=9
Y=SQRT9
Y=3 FOR THE WIDTH.
PROOF
5^2+3^2=36
25+9=36
36=36
