A rectangular library has a length os 36 feet and a perimeter of 116 feet what is the width in feet of the library

The width of the library is 22feet.

Perimeter = length+ length+ width+ width

The problem is telling us that the perimeter is 116 and the length is 36. So let’s plug it in and solve for width which equal w
w= width
Step 1: 116= 36+ 36+ w+w

Step 2: 116=72+ 2w

Step 3: 116= 72+2w
-72 -72

Step 4: 44=2w

Step 5: divide 2w on both sides ( 44 divided by 2)

Step 6: w= 22
