Answer:
area= 264.5 unit square
Step-by-step explanation:
let the width of the rectangle be x units then the length would be 2x units
perimeter = 2(l+b)= 2(2x+x)=2(3x)=6x
69=6x
x=69/6=11.5units
width is 11.5 units and length is 23 units
area= lxb= 11.5* 23= 264.5 units square
The markup is 8%, meaning it costs 8% more.
The starting price is 100%.
Therefore, the markup is 108% of $12.
If we multiply 12 by 108% (1.08), we will get our answer of $12.96
