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



and . 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.

L=W+8
2L+2W=24
2(W+8)+2W=24
2W+16+2W=24
4W=24-16
4W=8
W=8/4
W=2 ANS. FOR THE WIDTH.
L=2+8=10 ANS. FOR THE LENGTH.
PROOF:
2*10+2*2=24
20+4=24
24=24
