Question

The area of an equilateral triangle of side 8cm is

Answer 1

• Side=a=8cm

$\\ \sf\longmapsto Area=\dfrac{\sqrt{3}}{4}a^2$

$\\ \sf\longmapsto Area=\dfrac{\sqrt{3}}{4}(8)^2$

$\\ \sf\longmapsto Area=\dfrac{64\sqrt{3}}{4}$

$\\ \sf\longmapsto Area=16\sqrt{3}$

$\\ \sf\longmapsto Area=16\times 1.732$

$\\ \sf\longmapsto Area=27.7cm^2$
