Question 1107461: The Hillcrest Garden Club wants to double the area of its rectangular rose bed. Strips of the same width will be added to one end and one side to form a rectangle. If the bed is now 17.5m by 12.2m, what are the dimensions of the new bed?

You can put this solution on YOUR website!
the area of the original rectangle is 12.2 * 17.5 = 213.5 square meters.

the new rectangle will have a length of 12.2 + x and a width of 17.5 + x.

the new area will be 2 *( 231.5 = 427 square meters.

you get (12.2 + x) * (17.5 + x) = 427.

solve this quadratic equation to get x = 5.9832066662876.

your new width will be 18.18320667.

your new length will be 23.48320667.

your new area will be 427 square meters.

a picture of what your new rectangle will look like is shown below:

the original rectangle is ABCD.

the new rectangle is EFGD.
