Here is an example of an edited problem…
Question: Find the perimeter of the rectangle.                                 2 cm

5.7
5.7
2          The perimeter is 11.8.
+ 2
11.8

5.7
5.7
2.0          The perimeter is 15.4 cm.
+ 2.0
15.4
Perimeter is the sum of all the side lengths. I needed to line the decimals up in order
to add the side lengths correctly and my answer needed to have units of measure.
Question: What is the area of the rectangle?                                  2 cm

5.7 x 2 = 114     The area is 114 cm.

A = lw

5.7 x 2 = 11.4    The area is 11.4 cm2.

The area of a rectangle is length times width. Multiply 5.7 times 2 and make sure you
get the decimal in the right place. When giving units of measure for area, the units
must be squared.
