Question

The area of equilateral triangle is 163 cm2. Find the side of equilateral triangle.​

Answer 1

$\huge\tt\colorbox{red}{\color{navy}{answer}}$

$Area\;of\;equilateral\;triangle=163cm^2$

$formula\;of\; equilateral\;triangle=√3/4a^2$

$163=√3/4a^2$

$40.75÷√3=a^2$

$40.75÷1.732=a^2$

$23.52=a^2$

$a=4.84$

$side\;of\;equilateral\;triangle=4.84cm$

$\textbf{\huge{\red{Answer}} }$

Area of equilateral triangle = 163cm²

Formula of equilateral triangle = $\dfrac{√3}{4a²}$

$\implies$ 163 = $\dfrac{√3}{4a²}$

$\implies$ 40.75 ÷ √3 = a²

$\implies$ 40.75 ÷ 1.732 = a²

$\implies$ 23.52 = a²

$\implies$ a = 4.84

Side of equilateral triangle = 4.84cm
