The boy bent a piece of wire so that it formed a triangle with sides 8 cm, 3 cm and 6 cm long.

The boy bent a piece of wire so that it formed a triangle with sides 8 cm, 3 cm and 6 cm long. How long was this piece of wire? What is the perimeter of the triangle.

Given:
Triangle;
a = 8 cm;
b = 3 cm;
s = 6 cm;
l =?
P =?
1) To find the length of a piece of wire, add the lengths of the sides of the resulting triangle:
l = a + b + c;
l = 8 + 3 + 6 = 17 (cm);
2) The perimeter of a triangle is equal to the sum of its three sides.
P = a + b + c;
P = 8 + 3 + 6 = 17 (cm);
Answer: wire length – 17 cm; perimeter – 17 cm.
