2. The perimeter of a rectangular flower garden is 60 m and its area is 225 m2. Find the length of the garden.

Answer 1

Based on this drawing of the rectangular flower garden, the area of the garden will by X*Y, and the perimeter will be Y+X+Y+X, or P = 2X+2Y.

So now you have:

A = X*Y
P = 2X+2Y

if you solve the first equation to give X in terms of Y, you get X = A*Y
You then plug that into the perimeter equation to get:
P = 2*(X) + 2*Y or,
P = 2*(A*Y) + 2*Y

From there, you can solve for Y using your given A and P, and then solve for X using Y
