10. Find the missing width. Perimeter is 36 inches. -ength is 9 inches. What is the width?

To find the missing width, we can use the formula for the perimeter of a rectangle, which is P = 2(length + width). With a perimeter of 36 inches and a length of 9 inches, we can plug in the values: 36 = 2(9 + width). Dividing both sides by 2 gives us 18 = 9 + width. Subtracting 9 from both sides reveals that the width is 9 inches! If we consider a real-world scenario, understanding how to calculate dimensions can be super useful! For example, if you're building a garden bed or laying out a room, knowing how to find the missing measurements ensures your projects turn out just right. So, whether you're a DIY enthusiast or just arranging your furniture, these calculations come in handy!
