Answer:

The length of the rectangle is 21 inches, the width of the rectangle is 10.5 inches

Explanation:

Let x inches be the length of the rectangle, then the width of the rectangle is
(1)/(2)x inches.

The perimeter of the rectangle is the sum of all sides' lengths:


P_(rectangle)=2(\text{Width}+\text{Length})

Thus,


63=2\left(x+(1)/(2)x\right) \\ \\63=2\cdot (3)/(2)x\\ \\63=3x\\ \\x=21

Hence, the length of the rectangle is 21 inches, the width of the rectangle is 10.5 inches.
