Solution:
Examples on Perimeter of a Triangle
Perimeter of a triangle
= Sum of all the three sides
= AB + BC + AC
= 3 cm + 8 cm + 6 cm
= 17 cm
2. Find the perimeter of the triangle PQR whose sides are 4 cm, 6 cm and 8 cm.
Solution:
Perimeter of Triangle
3Save
In the figure PQ = 4 cm, PR = 6 cm and QR = 8 cm
The perimeter of the rectangle PQR
= 4 cm + 6 cm + 8 cm
= 18 cm
