To determine if the statement is true or false, we can calculate the perimeter of the triangle by adding the lengths of its sides.
The sides of the triangle are 20 cm, 12 cm, and 16 cm.
Calculating the perimeter: \[ \text{Perimeter} = 20 , \text{cm} + 12 , \text{cm} + 16 , \text{cm} = 48 , \text{cm} \]
Since the calculated perimeter is indeed 48 cm, the statement "The perimeter of a triangle of sides 20cm, 12cm, 16cm is 48cm" is:
True.
