The perimeter of the triangle is 64mm. The length of one side of the triangle is 5/16 of the perimeter

The perimeter of the triangle is 64mm. The length of one side of the triangle is 5/16 of the perimeter, and the length of the other side is 0.9 times the length of the first. Find the sides of the triangle.

1.Let’s find the first side of the triangle if it is known to be 5/16 of the perimeter:
64 mm * 5/16 = 20 mm.
2. Find the second side of the triangle if it is 0.9 times the length of the first side:
0.9 * 20mm = 18mm.
3. Find the third side of the triangle by subtracting the sum of the first two sides from the perimeter:
64 mm – (18 mm + 20 mm) = 64 – 38 = 26 mm.
Answer: The sides of the triangle are 20 mm, 18 mm and 26 mm.
