Question

Find the length of the side of an equilateral triangular garden whose perimeter is 66 m.

• A. 66 m
• B. 11 m
• C. 22 m
• D. 3 m

Answer 1

The correct option is C 22 m

Given perimeter = 66 m
Let one side of the equilateral triangle be $x$ m.
In an equilateral triangle, the length of all sides are equal.

$\therefore x+x+x=66m$
$\Rightarrow 3x=66$
$\Rightarrow x=22m$

$\therefore$ Length of the side of the equilateral triangle
$=22m$
