Question

A square garden has a side length that si 3 meters shorter than the length of a rectangular garden. Find the perimeter of the rectangular garden in terms of y

Answer 1

No idea what y is. However, if it is the side of the square, then the length of the rectangle is y+3

Now, since we have no idea of the width of the rectangle, let's call it z. Then the perimeter is

2(y+3 + z)

If the two gardens have the same area, then y^2 = (y+3)z so z=y^2/(y+3) and the perimeter is thus

2(y+3 + y^2/(y+3))

You fill in what was omitted, and work on i t, ok?

Answer 2

8+4y/y+3
