Answer:
Part 1) The dimensions of the actual object are [tex]50\ ft[/tex] by [tex]60\ ft[/tex]
Part 2) The area of the actual object is [tex]3,000\ ft^{2}[/tex]
Step-by-step explanation:
Part 1)
we have that
The scale is equal to
[tex]\frac{0.5}{10}\frac{in}{ft}[/tex]
rewrite the scale
[tex]\frac{10}{0.5}\frac{ft}{in}[/tex]
To find the dimension of the actual object multiply the scale by the dimensions of the model
so
[tex]\frac{10}{0.5}\frac{ft}{in}*2.5\ in=50\ ft[/tex]
[tex]\frac{10}{0.5}\frac{ft}{in}*3\ in=60\ ft[/tex]
Part 2)
Find the area
The area of rectangle is equal to
[tex]A=LW[/tex]
substitute
[tex]A=50*60=3,000\ ft^{2}[/tex]
