One side of the triangle is 3.7 cm, which is 0.9 cm more than the second side and 1.2 cm less than the third. Find the perimeter of the triangle.
It is known that the length of one of the sides of the triangle is 3.7 cm.
Using the data from the condition, we calculate the length of the second and third sides:
3.7 – 0.9 = 2.8 cm.
3.8 + 1.2 = 4.9 cm.
Let’s find what the perimeter is equal to:
P = 3.7 + 2.8 + 4.9 = 11.4 cm.
