Question

find the length of an equilateral traingle having side 2a

Answer 1

Q. Find the length of an equilateral triangle having side 2a.

Answer :

We know that,

Equilateral triangle is the triangle in which all the sides are equal.

Given :-
side = 2a

length of the equilateral triangle = Perimeter
= side + side + side
= 2a + 2a + 2a
= 6a

........................OR.........................

Perimeter = 3×side (in equilateral triangle)
= 3×2a
= 6a


Hence,
length of an equilateral triangle = 6a

Answer 2

$\to$ Length = 6a cm

$\large \bold{ \underline{ \underline{ \sf \: Explaination : \: \: \: }}}$

Given ,

$\star$ Side of equilateral triangle = 2a cm

According to the question ,

Length of equilateral triangle = Perimeter

$\to \sf Perimeter = 3 × Side \\ \\ \to \sf</p><p>Perimeter = 3 × 2a \\ \\ \to \sf</p><p>Perimeter = 6a \: cm</p><p>$

Hence , the length of given equilateral triangle is 6a cm
