Answer:
Part a) The area of the base is [tex]7,176\ in^{2}[/tex]
Part b) The area of the base is [tex]49\frac{5}{6}\ ft^{2}[/tex]
Step-by-step explanation:
we know that
The area of a rectangle is equal to
[tex]A=LW[/tex]
Part a)
we have
[tex]L=92\ in[/tex]
[tex]W=78\ in[/tex]
substitute
[tex]A=92*78=7,176\ in^{2}[/tex]
Part b)
we know that
[tex]1\ ft=12\ in[/tex]
Convert inches to feet
[tex]92\ in=92/12\ ft[/tex]
[tex]78\ in=78/12=6.5\ ft[/tex]
substitute in the formula
[tex]A=(92/12)*6.5=(598/12)\ ft^{2}[/tex]
Convert to mixed number
[tex](598/12)\ ft^{2}=(588/12)+(10/12)=49+(5/6)=49\frac{5}{6}\ ft^{2}[/tex]
