Answer: Option B.
Step-by-step explanation:
We know that her living room has the shape of a rectangle and its dimensions on the floor plan are:
[tex]1\ \frac{7}{8}\ in[/tex] by [tex]2\ \frac{1}{2}\ in[/tex]
We can convert from mixed numbers to decimal numbers:
[tex]1\ \frac{7}{8}\ in=(1+0.875)\ in=1.875\ in[/tex]
[tex]2\ \frac{1}{2}\ in=(2+0.5)\ in=2.5\ in[/tex]
We know the scale drawing of the floor plan of Trinity's house is [tex]\frac{80}{1}[/tex], then, we need to multiply the dimensions of her living room on the floor plan by [tex]\frac{80}{1}[/tex] in order to get the dimensions of her actual living room:
[tex](1.875\ in)(\frac{80}{1})=150\ in\\\\(2.5\ in)(\frac{80}{1})=200\ in[/tex]
Therefore, the dimensions of her actual living room are:
[tex]150\ in[/tex] by [tex]200\ in[/tex]
