Question

perimeter of an equilateral triangle is 24cm. it's area​

Answer 1

Answer:

side = 24/3= 8cm

area = 1/2*base*height

= 1/2 *3*3= 9/2

= 4.5

Answer 2

let the side be x

x+x+x=24

3x=24

x=8

hence the side is 8cm

Area = √3/4 × side²

$area = \frac{ \sqrt{3} }{4} \times 64$

$area = \sqrt{3} \times 16$

$area = 16 \sqrt{3} {cm}^{2}$
