The perimeter of the triangle is 6.4 cm. The length of one side is 0.35 of the perimeter

The perimeter of the triangle is 6.4 cm. The length of one side is 0.35 of the perimeter, and the length of the other side is 75% of the length of the first. How long is the side tray?

1) Find the first side of the triangle if it is known that it is 0.35 of the perimeter of the triangle, and the perimeter of the triangle is 6.4 cm.

6.4 * 0.35 = 2.24 cm.

2) Find the second side of the triangle if it is known that it is 75% of the length of the first side, and the length of the first side is 2.24 cm.

2.24 – 100%

X – 75%;

X = 2.24 * 75/100;

X = 1.68 cm.

3) Find out how long the two sides are.

1.68 + 2.24 = 3.92 cm.

4) Find the third side.

6.4 – 3.92 = 2.48 cm.

Answer: The length of the third side is 2.48 cm.
