The length of a rectangular room is 5 feet more than 3 times the width. The perimeter of the room is 62 feet. Find the dimensions of the room.

Step 1. The perimeter P means adding up all the four sides of a rectangle.

Step 2. Let w be the width.

Step 3. Let 3w+5 be the length since the length is 5 feet more than 3 times the width.

Step 4. Then, P=w+w+3w+5+3w+5=62.

Step 5. Solving yields the following steps

Done!



For w=6.5 , then 3w+5=24.5 and P=2(6.5+24.5)=62 which is a true statement.

Step 6. ANSWER: The width is 6.5 feet and the length is 24.5 feet.

I hope the above steps were helpful.
