The perimeter of a rectangle is 44 meters. The length is 2 meters more than the three times the width. Find the length.

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

Step 2. Let w be the width

Step 3. Let 3w be three times the width

Step 4. Let 3w+2 be the length since it is 2 meters more than three times the width

Step 5. Then P=w+w+3w+2+3w+2=8w+4=44 since the perimeter P is 44 meters.

Step 6. Solving the equation in Step 4 leads to the following steps

8w%2B4=44

Subtract four from both sides

8w%2B4-4=44-4

8w=40

Divide by 8 to both sides of the equation

8w%2F8=40%2F8

w=5 and 3w+2=15+2=17 and P=2(5+17)=44 which is a true statement.

Step 7. The length is 17 meters.

I hope the above steps and explanation were helpful.
