The rectangle has opposite sides of equal lengths. So, a rectangle with width "w" and length "l has a paerimeter of:


p=w+w+l+l=2w+2l

In this case, p = 372 cm and w = 88 cm, so we input these ans solve for l:


\begin{gathered} 372=2\cdot88+2l \\ 2l=372-176=196 \\ l=(196)/(2)=98 \end{gathered}

So, the length of the painting is 98 cm.
