Leah claims that these figures are not similar. When she compared the heights, she wrote 27. Then she compared the bases and got

Answer:
<h2>Leah is actually wrong, because those rectangles are similar.</h2>Step-by-step explanation:
Remember that similarity is about having proportional sides and congruent angles. When we have congruent sides, then those rectangles are congruent not similar.
In this case, to find the similarity, Leah should compare bases and heights thorugh division, because the ratio between heights and the ratio between bases must be equal. So, let's divide.
As you can observe, both ratios are equal.
Therefore, those rectangles are congruent.

Answer:
20 ft by 10ft
Step-by-step explanation:
Area of the garden =200 square feet
Let the dimensions of the garden be x and y
Area, xy=200
Since one side is already protected by a barn,
Perimeter of the garden=2x+y
The minimum point of P(y) is the point where its derivative equals zero.
y=20feet
Recall:
xy=200
20x=200
x=10feet
The dimensions of the garden that will require minimum fencing is 20 ft by 10ft
