The image you provided contains a geometric figure with a yellow region inside what appears to be two overlapping right triangles. The sides of the triangles are labeled as follows:

• One right triangle has sides of length 3 and 5, corresponding to the legs, and the hypotenuse is not given.
• Another right triangle has sides of length 6 and 8, with the hypotenuse also not labeled.

Objective

We need to find the area of the yellow quadrilateral formed between these two right triangles.

Plan

1. Use the Pythagorean Theorem to find the hypotenuses of both triangles.
2. Apply geometric methods to decompose or relate the area of the yellow region to the triangles.

Let's begin by calculating the hypotenuses of the two triangles using the Pythagorean theorem.

For the smaller triangle: $\text{Hypotenuse} = \sqrt{3^2 + 5^2}$

For the larger triangle: $\text{Hypotenuse} = \sqrt{6^2 + 8^2}$

I'll calculate these values now.The hypotenuses are as follows:

• For the smaller triangle (with sides 3 and 5), the hypotenuse is approximately $5.83$.
• For the larger triangle (with sides 6 and 8), the hypotenuse is exactly $10$.

Next, to find the area of the yellow region, we can use the fact that the yellow quadrilateral is formed inside these two right triangles. Given the arrangement, it looks like the yellow region is a trapezoid, and we will apply a formula that uses the known dimensions to calculate its area. I'll compute that now.Since the yellow quadrilateral resembles a trapezoid, we can use the trapezoid area formula:

$\text{Area of trapezoid} = \frac{1}{2} \times ( \text{Base}_1 + \text{Base}_2 ) \times \text{Height}$

• Base_1 is 5 (left vertical side),
• Base_2 is 6 (right vertical side), and
• Height is the distance between the two bases, which is given as 3.

Let me now calculate the area of the yellow trapezoid.The area of the yellow quadrilateral (trapezoid) is $16.5$ square units.

3. Can the yellow region be divided into smaller triangles for an alternative method of calculation?
4. How do you find the height of a trapezoid if it's not directly given?
5. What are some other methods for finding the area of irregular shapes?

Tip: Whenever dealing with right triangles, the Pythagorean theorem is a reliable tool for calculating missing side lengths.
