Question

find the area of an equilateral triangle whose each side is 12 cm. also find the height of the triangle​

Answer 1

The area of na equilateral triangle is given by √3 /4 a²

In this case, a is 12 cm

Area =√3/4×(12)²

=36√3 cm²

Area =1/2× base×height

= 1/2 ×12× height

1/2 ×12 × height =36√3

Height =6√3

Answer 2

Step-by-step explanation:

area of equ. triangle =

$\frac{ \sqrt{3} }{4 } \times {side}^{2}$

$\frac{ \sqrt{3} }{4} \times {12}^{2}$

$\frac{ \sqrt{3} }{4} \times 144$

=

$36 \sqrt{3}$
