If it tells you whats the perimeter, just add all sides up.

If it says to you whats the AREA just multiply the lenght by the width or lenght by high because its not 3D

Perimeter:outside

Area:inside

Let w and l be the length and height of the rectangle.

We know that:

$\begin{cases}l = 2w-5\\2(l+w)=26\end{cases}$

Substitute the first equation in the second:

$2(l+w)=26 \iff l+w=13 \iff 2w-5+w=13 \iff 3w = 18 \iff w=6$

Use the first equation to compute the length:

$l=2\times 6 - 5 = 12-5=7$

So, length = 7 cm; width = 6 cm
