Find and interpret perimeter and circumference in numeric and contextual problems.
Put both boundary measures into a comparable form
Problem
A circular garden has radius \(5~\text{meters}\), and a rectangular garden is \(8~\text{meters}\) by \(7~\text{meters}\). Calculate \(\text{both}~\text{boundary}~\text{measures}\) to the nearest tenth, and compare them.
Big Picture
What this problem is really about
A fair comparison begins by measuring the same feature of both gardens: their complete boundary lengths. Use the radius form of circumference for the circle and the doubled length-plus-width structure for the rectangle, then express both results to the requested decimal place. Comparing only after rounding consistently keeps the formulas, units, and precision aligned.
