Answer:
[tex]1\dfrac{3}{32}\ \text{inches}^2[/tex]
[tex]4\dfrac{1}{4}\ \text{inches}[/tex]
Step-by-step explanation:
w = Width of a stamp = [tex]\dfrac{7}{8}\ \text{inch}[/tex]
l = Length of a stamp = [tex]1\dfrac{1}{4}\ \text{inch}[/tex]
Area is given by
[tex]A=lw\\\Rightarrow A=\dfrac{7}{8}\times 1\dfrac{1}{4}\\\Rightarrow A=\dfrac{7}{8}\times \dfrac{5}{4}\\\Rightarrow A=\dfrac{35}{32}\\\Rightarrow A=1\dfrac{3}{32}\ \text{inches}^2[/tex]
The area of each stamp is [tex]1\dfrac{3}{32}\ \text{inches}^2[/tex]
Perimeter is given by
[tex]P=2(l+w)\\\Rightarrow P=2(\dfrac{7}{8}+\dfrac{5}{4})\\\Rightarrow P=2\times \dfrac{17}{8}\\\Rightarrow P=\dfrac{17}{4}=4\dfrac{1}{4}\ \text{inches}[/tex]
The perimeter of each stamp is [tex]4\dfrac{1}{4}\ \text{inches}[/tex].
