Width= 32 centimeters
Step-by-step 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
so, the width is 32 centimeters.
