Question 1: Find the perimeter of the triangle having 12 cm, 22 cm and 25 cm. Solution:
Let A = 12 cm, B = 22 cm, C = 25 cm. The formula to find the perimeter of a triangle is P = A + B + C Plugging the given values we get P = 12 + 22 + 25 P = 59 cm. Therefore the perimeter of a triangle is P = 59 cm.
Question 2: Find the value of A if P = 29, b = 6 and c = 14 Solution:
Here for the given problem we need to find the value of 'A'.
As we know, the formula to find the perimeter is P = A + B + C Plug in the know values to find the value of A. 29 = A + 6 + 14 29 = A + 20 A = 9
Therefore the value of 'A' for the given problem is 9.
