Answer to Problem 1C
It is a scalene triangle
Explanation of Solution
Given information:
Perimeter of the triangle is given as 65 Cm
Length of third side is given as 20 cm
Length of first side is twice the length of the second side
Calculation:
Let the length of the first side be x
Length of the second side will be 2x
Hence, this gives us-
Add both x together
Subtract 20 from both the sides
This gives us −
Now, divide both sides by 3
This will give us-
So the length of first side is 15cm
Length of the second side is 2x, multiply 2 with 15.
So the length of the second side is 30 cm
Length of third side is given as 20 cm
Conclusion- Since, all the three sides of the triangle are different it is a scalene triangle.
