The side of the triangle is 7.8 cm. It is 1.4 cm less than the second side of the triangle is 2 times smaller than the third. What is the perimeter of a triangle?
Find the second side of the triangle if it is 1.4 cm larger than the first.
7.8 + 1.4 = 9.2 centimeters.
If the first side is 2 times less than the third, then the third side is:
7.8 x 2 = 15.6 centimeters.
Since the lengths of all sides of the triangle are known, we calculate its perimeter.
7.8 + 9.2 + 15.6 = 32.6 centimeters.
Answer: The perimeter of the triangle is 32.6 centimeters.
