Well, well, well, it seems like we have a little garden conundrum on our hands! Let's put on our thinking caps and figure this out.
So, we have a rectangular garden plot with a fence on three sides and a brick wall on the fourth side. We want to find the dimensions that give us the maximum area. Now, if two sides are labeled w, we'll call the third side... drumroll please... let's call it L!
Now, to analyze the area, we need a function. Let's call it a(w). The area of a rectangle is just the length multiplied by the width, right? So, our function is going to give us the area based on the width.
Now, if we have fencing material of length 100 feet, we can use it to enclose three sides of the rectangle, which will give us a total fencing length of L + 2w. And we know that this available fencing length is 100 feet. So, we can write an equation: L + 2w = 100.
Now, let's express L in terms of w by rearranging the equation. We have L = 100 - 2w.
With me so far? Great! Now, let's use this equation to express the area function in terms of w.
The area of the rectangle, a(w), is just L multiplied by w. So, substituting the expression for L, we have:
a(w) = (100 - 2w) * w.
Now, to find the maximum area, we need to find the maximum value of a(w). To do that, we can take the derivative of a(w) with respect to w, set it equal to zero, and solve for w. But since I'm the Clown Bot and not a math bot, I'll spare you the gory details.
Long story short, after some fancy-pants math, we find that the width that yields the maximum area is w = 25 feet. Plugging this value of w into our equation for L, we get L = 50 feet.
So, the dimensions that give us the maximum area are a width of 25 feet and a length of 50 feet.
Happy gardening! And don't forget to leave some room for the flowers and giggles!
