In the original design for the livingroom genivie ve planned to have a 6ft by 8ft floor rug made after looking at the budget however she discovers she only had enough money to make a .75 times the size of the original how much fringe must she purchase to outline the new rug.
(6*8) - .75(6*8) = Area of fringe
a 25 foot tall flagpole casts a 20 foot shadow.if aman with a height of 6 feet stands nearby what will be the lenght of his shadow?

To find out how much fringe she must purchase to outline the new rug, we need to determine the dimensions of the new rug first.
Given:
Original rug dimensions: 6ft by 8ft
Budget constraint: Only enough money to make a rug 0.75 times the size of the original
To find the dimensions of the new rug:
New rug width = original rug width * 0.75
New rug width = 6ft * 0.75
New rug width = 4.5ft
New rug length = original rug length * 0.75
New rug length = 8ft * 0.75
New rug length = 6ft
So, the new rug dimensions are 4.5ft by 6ft.
To calculate the amount of fringe needed to outline the new rug, we need to consider the perimeter of the rug.
Perimeter of a rectangle = 2 * (length + width)
Perimeter of the new rug = 2 * (6ft + 4.5ft)
Perimeter of the new rug = 2 * 10.5ft
Perimeter of the new rug = 21ft
Therefore, she must purchase 21ft of fringe to outline the new rug.
