Answer:
The price per square foot is $0.50
Step-by-step explanation:
step 1
Find the area of the canvas
The area of the rectangular canvas is equal to
[tex]A=LW[/tex]
we have
[tex]L=4\frac{1}{2}\ ft= 4+\frac{1}{2}=\frac{4*2+1}{2}=\frac{9}{2}\ ft[/tex]
[tex]W=2\ ft[/tex]
substitute
[tex]A=(\frac{9}{2})(2)=9\ ft^2[/tex]
step 2
Find the price per square foot
Divide the cost by the area
so
[tex]\frac{4.50}{9}=\$0.50\ per\ square\ foot[/tex]
