Which choice shows the correct perimeter for the rectangle?

•  $\frac{3}{4}+\frac{3}{4}+\frac{2}{5}+\frac{2}{5}=\frac{10}{5}=2\ m$  

•  $\frac{3}{4}\times\frac{2}{5}=\frac{6}{20}=\ \frac{3}{10}\ m^2$  

•  $\frac{3}{4}+\frac{3}{4}+\frac{2}{5}+\frac{2}{5}=\frac{10}{4}\ =\ \frac{5}{2}=2\ \frac{1}{2}\ m$  

•  $\frac{15}{20}+\frac{15}{20}+\frac{8}{20}+\frac{8}{20}=\frac{46}{20}\ =\ 2\ \frac{6}{20}=2\frac{3}{10}m$  

•  $\frac{3}{4}+\frac{3}{4}+\frac{2}{5}+\frac{2}{5}=\frac{10}{18}=\frac{5}{9}m$  

If the perimeter of this shape is 30cm, what is the length of the missing side?

What is the area of a rectangle with a length of ²/₃ inch and a width of ¹/₂ inch? (Reduce your answer, if possible.)

• $\frac{2}{9}\ in^2$

• $\frac{2}{5}\ in^2$

• $\frac{1}{3}\ in^2$

• $\frac{7}{6}in^2$

Which choice shows the correct way to find the area of the rectangle?

•  $4\ \times\ \frac{3}{2}\ =\ \frac{12}{8}=\ 1\ \frac{4}{8}\ =\ 1\ \frac{1}{2}in^2$  

•  $4\ +\ 4\ +\ 1\ \frac{1}{2}+1\ \frac{1}{2}\ =\ 11\ in$  

•  $\frac{4}{1}\times\frac{3}{2}=\frac{12}{2}=6\ in^2$  

•  $4\ \times1\ \frac{1}{2\ }\ =\ 4\ \frac{1}{2}in^2$
