The perimeter of the triangle is 96 cm. The length of one side is 26 cm. The second is 7 cm less. What is the length of the third side.
The perimeter is the sum of the lengths of all sides of a geometric shape.
If it is known that the length of one of the sides of the triangle is 26 cm, and the second is 7 cm less, then we find the length of the second side of the triangle.
26 cm – 7 cm = 19 cm is the length of the second side.
The triangle has three sides. It is known that the length of the first side is 26 cm, the second – 19 cm. From this you can find the third side of the triangle.
26 cm + 19 cm = 45 cm – the sum of the two lengths of the triangle.
96 cm – 45 cm = 51 cm is the length of the third side of the figure.
Answer: 51 cm.
