Question

if the length of each side of an equilateral triangle is 1 cm then its perimeter is equal to​

Answer 1

Step-by-step explanation:

p=a+b+c

p=1+1+1

p=3

: perimeter of equilateral triangle is 3.

Answer 2

$\bold{\huge{\underline{Question:}}}$

→ If the length of each side of an equilateral triangle is 1 cm, then it's perimeter is equal to ?

Answer : $\boxed{\huge{\bf{\pink{3\:cm}}}}$

$\textbf{\underline{\underline{Step-by-step\:Explanation:}}}$

Perimeter of equilateral triangle

= Side × 3

= 1 × 3

= 3 cm.

or

→ Perimeter of equilateral triangle = sum of all three sides.

= 1 + 1 + 1

= 3 cm.

∴ Perimeter of the given equilateral triangle is 3 cm.

$\sf\blue{\underline{\underline{Additional\:Information:}}}$

→ There are three types of triangles :-

• Scalene triangle ( all three sides are different )
• Isosceles triangle ( two sides are equal )
• Equilateral triangle ( all the three sides are equal ).

→ The sum of every triangle's interior angles is 180°
