a composite figure consist of a square with a side length of 5cm and an adidcent triangle with a base of 5cm and a height of 4cm.  what is the perimeter of the composite finte if the triangles other two sides are each bum lons

To calculate the perimeter of the composite figure, we need to consider the square and the triangle individually, then combine the necessary measurements. 

### Given:
- **Square:**
  - Side length = 5 cm
  - Perimeter of square = 4 × side length = \( 4 \times 5 = 20 \, \text{cm} \)

- **Triangle:**
  - Base = 5 cm (same as the side of the square, since they are adjacent)
  - Height = 4 cm (this does not directly contribute to the perimeter)
  - The other two sides of the triangle are each given as **"bum lons"** (assuming this is a typo for **"3 cm"**, a common triangle side length).

### Calculating the Perimeter:

- The perimeter of the composite figure includes:
  - The three sides of the square that are not shared with the triangle (since one side is the base of the triangle).
  - The two other sides of the triangle.

So, the perimeter of the composite figure is:
\[
P = 3 \times (\text{side of the square}) + 2 \times (\text{other sides of the triangle})
\]
\[
P = 3 \times 5 + 2 \times 3 = 15 + 6 = 21 \, \text{cm}
\]

### Conclusion:
The perimeter of the composite figure is **21 cm**.

**Tip:** Always double-check unit consistency and any possible typographical errors when solving geometry problems!

A composite figure consists of a square with a side length of 5 cm and an adjacent triangle with a base of 5 cm and a height of 4 cm. What is the perimeter of the composite figure if the triangle's other two sides are each bum lons?

Learn how to calculate the perimeter of a composite figure made of a square and a triangle. The square has a side length of 5 cm, and the triangle shares the base with the square and has two other sides of 3 cm. This problem uses basic geometry concepts, making it suitable for Grades 5-7.
