Inscription a rectangle with sides 3cm and 4cm. divide it by a segment into two triangles. find the perimeter of one of the triangles

4 cm and 3 cm are the sides of the rectangle.

We find the length of the diagonal using the Pythagorean theorem.

c ^ 2 = a ^ 2 + b ^ 2.

3 ^ 2 + 4 ^ 2 = 9 + 16 = 25.

25 = 52.

5 cm – the diagonal of the rectangle and the side of the triangle.

P tr = a + b + c.

P tr = 3 + 4 + 5 = 12.

12 cm is the perimeter of one of the triangles.

Solution: 12 cm perimeter of one of the triangle.
