Question

the perimeter of equilateral Triangles is 450 M find its area and altitude using under root 3 is equal to 1.73

Answer 1

Perimeter of equilateral triangle = 450 m

3 * side = 450

side = 450/3 

side= 150 m 


Now,

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

Area = $150$×$150$×$\frac{ \sqrt{3} }{4}$

Area = $75$×$75$×$\sqrt{3}$


Area of equilateral triangle = 5626√3 $m^2$


Then,

Altitude  by pythagoras theorem,

Now,

$(75)^2 + height^2 = 150^2$

5625 + $height^2= 22500$


$height^2 = 22500-5625$

height = $\sqrt{16875}$ m
