you want to expand the garden by planting a border of flowers. the border will have the same width around the entire garden.the flowers you brought will fill an area of 276sq.ft. How wide should the border be?
The inside is 24ft by 16ft but i need to find x.

It will be very helpful to draw a diagram to model this situation.
Since you're given the dimensions of the garden, calculate the area of the entire garden.
Subtract the given area of the flowers to get the area of the "inside of the garden."
The width of the flower border is x. Now write an equation for the area of the inside of the garden using x. (Refer to your diagram to help you.) What equation do you get? 
i found the answer x=3 but i don't kno how to show my work. lol

Show your work by writing an equation to model the situation. This will set you on the right track...
(I made a mistake. The border is an addition, so this is the correct info...)
It will be very helpful to draw a diagram to model this situation.
Since you're given the dimensions of the garden, calculate the area of the garden without the border addition.
Add the given area of the flowers to get the area of the entire garden with the addition.
The width of the flower border is x. Now write an equation for the area of the entire garden with the border addition using x. (Refer to your diagram to help you.) What equation do you get?
