Question

A square of area 36 ${cm}^2$ has the same perimeter as that of an equilateral triangle. What is the length of the side of the equilateral traingle?

Answer 1

let the side of a square $a$

Area$=a^2=36\Rightarrow a=6cm$

perimeter = $4\times 6=24cm=3\times x$

$x=\frac{24}{3}=8cm$

$\therefore$ Length of the side of the equilateral triangle$=8cm$
