Answer:
[tex]\mathrm{The\:third\:option:\:\:A = 47 \dfrac{ 1 }{ 2 }\:ft}[/tex]
Step-by-step explanation:
Area of a parallelogram: A = b × h
Since we know both the base and height, we can set up the equation, in order to solve for the area
b = base = 9 [tex]\frac{1}{2}[/tex] or 9.5
h = height = 5
A = b × h
Substitute the numbers into the equation
[tex]A = 9 \dfrac{ 1 }{ 2 } \times 5[/tex]
[tex]\mathrm{Turn\:9 \dfrac{ 1 }{ 2 }}\:\mathrm{into\:an\:improper\:fraction}[/tex]
[tex]A = \dfrac{ 19 }{ 2 } \times 5[/tex]
[tex]\mathrm{Turn\:5}\:\mathrm{into\:a\:fraction}[/tex]
[tex]A = \dfrac{ 19 }{ 2 } \times \dfrac{ 5 }{ 1 }[/tex]
[tex]\mathrm{Multiply\:19\:by\:5\:and\:2\:by\:1}[/tex]
[tex]A = \dfrac{ 95 }{ 2 }[/tex]
[tex]\mathrm{Turn\: \dfrac{ 95 }{ 2 } \:into\:a\:mixed\:number}[/tex]
[tex]A = 47 \dfrac{ 1 }{ 2 }[/tex]
[tex]\mathrm{The\:third\:option:\:\:A = 47 \dfrac{ 1 }{ 2 }\:ft}[/tex]
