The Deep Dive
To solve the problem, let's denote the width of the rectangle as \( w \). According to the given information, the length \( l \) can be expressed as \( l = 3w + 2 \). The formula for the perimeter \( P \) of a rectangle is \( P = 2(l + w) \). With the perimeter set to 100 meters, we plug in the values: \[ 100 = 2((3w + 2) + w) \] This simplifies to: \[ 100 = 2(4w + 2) \implies 100 = 8w + 4 \implies 96 = 8w \implies w = 12 \, \text{meters}. \] So the width of the rectangle is indeed **12 meters**. Let’s celebrate that mathematical win! The relationship between length and width here was a clever twist, revealing how the dimensions worked together, like a team finding their rhythm. Keep in mind that geometry can often feel like a puzzle, so don’t hesitate to draw it out to visualize the problem! Understanding the concept of perimeter can also be useful in real-life situations. For example, if you’re planning a garden, knowing how to calculate the perimeter helps in figuring out how much fencing you'll need. That skill transforms mathematical practice from the classroom to practical, everyday applications—talk about a win-win situation!
