The length of two sides of a triangle are 12.3 cm and 8.9 cm. If its perimeter is 26.7 cm,
find the length of the third side.
Answers
Answer:
The length of the third side = 5.5 cm
Step-by-step explanation:
Given that:
- The length of two sides of a triangle are 12.3 cm and 8.9 cm.
- Perimeter of a triangle = 26.7 cm
To find:
The length of the third side.
Formula used:
Perimeter of triangle = Sum of its three sides
Let the third side of the traingle be x cm.
According to the question:
→ 12.3 + 8.9 + x = 26.7
→ 21.2 + x = 26.7
→ x = 26.7 - 21.2
→ x = 5.5
∴ Third side of the traingle = x = 5.5 cm
