Find max area of rectangle inside a right triangle.

In summary, the problem is asking to find the area of the largest rectangle that can fit in a right triangle with legs of 5cm and 12cm. The two sides of the rectangle will be along the legs of the triangle. The solution involves creating an equation by comparing two similar triangles and then solving for either x or y and plugging it into the area expression.

Hi Brown Arrow! :smile:

(pleeeeeeease don't post such wide pictures! :redface:)

I don't get why he did the ratio …

he wanted an equation relating x and y, and he got it by comparing the two similar triangles :wink:

Now solve the ratio equation for x or y & plug the result into the expression for area.
 

1. What is the formula for finding the maximum area of a rectangle inside a right triangle?

The formula for finding the maximum area of a rectangle inside a right triangle is 1/2 * base * height, where the base and height of the rectangle are the sides of the right triangle.

2. How do you determine the base and height of the rectangle inside a right triangle?

The base and height of the rectangle can be determined by drawing an altitude from the right angle of the triangle to the hypotenuse. The base of the rectangle will be the length of the altitude, and the height will be the remaining portion of the hypotenuse.

3. Can the maximum area of a rectangle inside a right triangle be found using the Pythagorean theorem?

Yes, the maximum area of a rectangle inside a right triangle can be found using the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides.

4. How does the positioning of the rectangle inside the right triangle affect its maximum area?

The positioning of the rectangle inside the right triangle does not affect its maximum area, as long as the base and height of the rectangle are formed by the sides of the right triangle. The maximum area will always be 1/2 of the product of the base and height.

5. Can the maximum area of a rectangle inside a right triangle be greater than the area of the right triangle itself?

Yes, the maximum area of a rectangle inside a right triangle can be greater than the area of the right triangle itself, as long as the rectangle is not overlapping any of the sides of the triangle. In this case, the rectangle would be considered a separate shape and its area can be calculated using the aforementioned formula.
