The first side of the triangle is 4 3/10 cm, and the second side is 2 1/10 cm longer than the first.

The first side of the triangle is 4 3/10 cm, and the second side is 2 1/10 cm longer than the first. Find the longest of the third side if the perimeter of the triangle is 16 cm.

Given:
The first side of the triangle is 4 3/10 centimeters.
The second side of the figure is 2 1/10 centimeters larger than the first.
The perimeter of the triangle is 16 centimeters.

Let’s convert all data into millimeters:
1 cm = 10 mm.
4 3/10 cm = 43 mm.
2 1/10 cm = 21 mm.
16 cm = 160 mm.

Let’s calculate the length of the second side of the triangle:
43 + 21 = 64 millimeters.
Find the extent of the third side of the figure:
160 – 43 – 64 = 117 – 64 = 53 millimeters.
Answer: The length of the third side is 53 millimeters.
