The length of a rectangle is 8 in. more than its width. the perimeter of the rectangle is 24 in. what and the width and length of the rectangle?
Step 1. Perimeter P means adding up all 4 sides of a rectangle.
Step 2. Let w be the width.
Step 3. Let w+8 be the length.
Step 4. Then, P=w+w+w+8+w+8=24 since the perimeter is 24 inches
Step 5. Solving P=w+w+w+8+w+8=24 yields the following steps
Subtract 16 from both sides of the equation
Divide by 4 to both sides of the equation
. Check Perimeter
which is a true statement.
Step 5. ANSWER: The width is 2 inches and the length is 10 inches.
I hope the above steps were helpful.
