We need to use the following formula for the calculations:

Perimeter of rectangle:

$\overline{){\mathbf{P}}{\mathbf{\hspace{0.17em}}}{\mathbf{=}}{\mathbf{}}{\mathbf{2}}\mathbf{(}\mathbf{L}\mathbf{}\mathbf{+}\mathbf{}\mathbf{W}\mathbf{)}}$

Area of rectangle:

$\overline{){\mathbf{A}}{\mathbf{}}{\mathbf{=}}{\mathbf{}}{\mathbf{LW}}}$

If you are asked to provide a set of two or more numeric answers, separate them with commas. For example, to provide the year that *Sputnik* (the first satellite to be sent into orbit around the Earth) was launched and the year humans first walked on the Moon, you would enter 1957,1969 in the answer box.

A rectangle has a length of 5.50 m and a width of 12.0 m. What are the perimeter and area of this rectangle?

Enter the perimeter and area numerically separated by a comma. The perimeter should be given in meters and the area in square meters. Do not enter the units; they are provided to the right of the answer box.
