➭ We know that sides of equilateral Δs are equal.

We will use here formula :-

$\large{\underline{\boxed{\bf{\orange{Area \: of \: equilateral \: {\triangle} \: = \: {\frac{{\sqrt{3}}}{4}} {\times} Side^{2}}}}}}$

_________________[Put Values]

Area = √3 * (10)²/4

⇒ Area = √3 * 100 / 4

⇒ Area = 173.2/4

⇒ Area = 43.3

⇒ Area = 43.3 cm²

$\large{\star{\boxed{\boxed{\bf{\purple{Area \: = \: 43.3cm^{2}}}}}}}$
