One side of the triangle is 46.3 cm, the other 16.7 cm less than the first and 14.9 cm less than thirds. Find the perimeter of the triangle.

Since the first side is 46.3, and the second side is 16.7 less, then we find the second side:
46.3-16.7 = 29.6 (second side)
because the second side is 14.9 cm smaller than the third, then the third side is 14.9 cm larger than the second side, therefore we can find the third side:
29.6 + 14.9 = 44.5 (third party)
Now that we know all the sides of the triangle, we can find its perimeter using the formula:
P = a + b + c
P = 46.7 + 29.6 + 44.5 = 120.8 cm
Answer: the perimeter of the triangle is 120.8 cm
