___________________________

TO FIND

Length Of It's Sides

___________________________

EQUILATERAL TRIANGLE

• All sides of equilateral triangle are same.

• All angles of equilateral triangle are of 60°.

___________________________

We know that,

Perimeter Of Equilateral Triangle = 3 × Side

Perimeter Of Equilateral Triangle = 3 × Side

Side = Perimeter Of Equilateral Triangle / 3

Side = 2.55 / 3

Side = 0.85

Side = 0.85 m

Side = 85 cm

Answer 2

answer perimeter = 2m25cm =255cm , perimeter of equilateral triangle = 3×length of side , 255=3× length of side , length of side = 255÷3 =85cm
