If the length of a rectangle is 96ft and the perimeter is 397ft. What is the width?

Step 1. Let l = 96 ft length of rectangle and w be the width

Step 2. Let P = 397 be the perimeter. Perimeter means adding the 4 sides of a rectangle. So,

P=l%2Bl%2Bw%2Bw

P=96%2B96%2B2w=397

P=192%2B2w=397

Step 3. Subtract 192 from both sides of equation to get 2w by itself

192%2B2w-192=397-192

2w=205

Step 4. Divide 2 to both sides of equation

2w%2F2=205%2F2

w=+205%2F2+=+102.5

Step 5. w = 102.5 is the width of the rectangle.

Check P=192+2w=192+2(102.5)=192+205=397. So w = 102.5 is the solution.
