Question

Calculate the perimeter of a triangular plot whose sides are 7 cm , 8cm , 12 cm​

Answer 1

Answer:

$\sf \green {\therefore \: Perimeter \: of \: a \: triangular \: plot}$

$\sf \green {= 27 \: cm}$

Step-by-step explanation:

Perimeter of a triangle ( scalene ) = S + S + S

= 7 cm + 8 cm + 12 cm

= 27 cm

More to learn:

• Perimeter of a triangle ( isosceles ) = 2 ( S ) + S

• Perimeter of a triangle

( equilateral ) = 3S ( 3 × S )

• Area of a triangle = ½ × B × H
