Question

Ig the area of an equilateral triangle is 43.25 sq. cm,
find the measure of each of its sides. (Take √3 = 1.73)​

Answer 1

given , area of equilateral triangle = 43.25

side = ?

we know that area of triangle = ( root 3/4) a^2

=> 43.25 = (1.73 /4) a^2

=> 173 = (1.73) a^2

=> 100 = a^2

=> a =10
