If the area of an equilateral triangle is 25√3 cm², then the length of each side of the triangle is:

A10 cm

B5 cm

C12 cm

D8 cm

Answer:

A. 10 cm

Read Explanation:

equilateral triangle area=a234\frac{a^2\sqrt3}{4}

a234=253\frac{a^2\sqrt3}{4}=25\sqrt3

a2=25×4a^2=25\times4

a=5×2=10a=5\times2=10
