A square has all it sides equal. Each side is equals to 5 inches .
total length of the square = 5 + 5 + 5 + 5 = 20 inches
The newly formed rectangle has the same perimeter as the square. Therefore,
perimeter = 20 inches
length = 6 inches
width ?
[tex]\begin{gathered} \text{perimeter =}2(l+w) \\ 20=2(6+w) \\ 20=12+2w \\ 20-12=2w \\ 8=2w \\ w=\frac{8}{2} \\ w=4\text{ inches} \end{gathered}[/tex]
width = 4 inches
