Answer 1

The perimeter of a triangle ABC

Perimeter of a Triangle

= AB + BC + CA

= 2 cm + 4 cm + 3 cm,

(add the length of each side of the triangle).

= 9 cm

Perimeter of the triangle = Sum of the sides.

Answer 2

❁Solution :

${\mapsto{ \bf{perimeter \: of \: the \: triangle = a + b + c}}}$

$= 3.2 + 4.1 + 6 \\ = 7.3 + 6 \\ = 13.3$

$\bf \: thus \: answer \: is{ \fbox{13.3}}$

Extra information:

Perimeter Formula :

1. perimeter of rectangle = 2(l+b)
2. perimeter of square = 4× side
3. perimeter of triangle = a+b+c

Area Formula :

1. Area of rectangle = l×b
2. Area of square = side × side
3. Area of triangle = 1/2 ×b×h .
