Question

find the area of a equilateral triangle whose each side is 16cm

Answer 1

Answer:

the area of an equilateral triangle is 64√3 cm².

Step-by-step explanation:

Area of an equilateral triangle =√3/4x² (where x=side )

Area of an equilateral triangle=√3/4 *(16)²

                                                 =√3/4 *16*4*4

                                                 =√3*16*4

                                                 =64√3 cm²

Hence, the area of an equilateral triangle is 64√3 cm².

Answer 2

Answer:

$\boxed{\sf{Area=110.85cm^2}}$

Step-by-step explanation:

$\textsf{Given :}$

$\textsf{side = 16 cm}$

$\underline{\mathfrak{Formula}}$

$\mathsf{Area=\frac{\sqrt{3}}{4}side^2}$

$\mathfrak{\underline{Area}}$

$\mathsf{Area=\frac{\sqrt{3}}{4}side^2}$

$\mathsf{\implies\frac{\sqrt{3}}{4}(16)^2}$

$\mathsf{\implies\frac{\sqrt{3}}{4}\times256}$

$\mathsf{\implies\sqrt{3}\times 64}$

$\mathsf{\implies1.732\times 64}$

$\mathsf{\implies110.848}$

$\mathsf{\implies110.85}$
