Practice 8Quick check
What is the perimeter of a rectangle that is \(9\) m by \(3\) m?
\(2 \times (9 + 3) = 24\). The answer \(27\) is the area, in square meters.
Practice 9Quick check
A square has an area of \(49 \text{ cm}^2\). How long is each side?
The side times itself must give \(49\), and \(7 \times 7 = 49\).
All done?
If you got most of them right, you're ready to move on. If not, reread the lesson and try the ones you missed again in a few days.
