## Homework Statement

Hello!

It seems that I don't know the correct approach to this problem.

Sally wants to plant a vegetable garden along the side of her home. She doesn't have any fencing, but wants to keep the size of the garden to 100 square feet.

a) What are the dimensions of the garden which will minimize

the amount of fencing she needs to buy?

b) What is the minimum amount of fencing she needs

to buy? Round your answers to the nearest foot. (Note: Since one side of the garden will

border the house, Sally doesn't need fencing along that side.)

## Homework Equations

My thoughts:

x - width of the garden

l - length

Since one wall is not required, the fencing = 2x + l

area = x*l = 100, hence l = 100/x

Have no idea how to proceed to solve a) and b) (without calculus, based only on precalculus program).

Thank you!
