Width= 32 centimeters
Explanation
Step 1
Let
Width=unknown value= W
Length=L=26 centimeters
Perimeter(is the distance around the edge of a shape)= 2L+2W( two purple line+two green line),then
P=2L+2W
Step 2
find w using L= 26 and P=116 in the equation for the perimeter
[tex]\begin{gathered} P=2L+2W \\ 116=2\cdot26+2W \\ 116=52+2W \\ \text{subtract 52 in both sides} \\ 116-52=52+2W-52 \\ 64=2W \\ \text{divide both sides by 2 } \\ \frac{64}{2}=\frac{2W}{2} \\ 32=W \end{gathered}[/tex]so, the width is 32 centimeters.
I hope this helps you.
