Question

Area of an equilatral triangle is 25root 3cm².find perimeter of triangle

Answer 1

Answer:

Step-by-step explanation:

area of an equlateral triangle=sqrt(3)/4*(a^2)

given area=25sqrt(3)cm^2

(sqrt(3)/4)*(a^2)=25*sqrt(3)

a^2=25*4

a=5*2=10

now perimeter of an equilateral triangle=3a=3*10=30cm

Answer 2

Answer:

30cm

Step-by-step explanation:

area=25√3cm^2

√3/4a^2=25√3

a^2=25×4

a=10

perimeter=3a=3(10)

=30cm
