|
Answer» The Answer is 6 cmStep-by-step explanation:AnswerSince , ΔABC is an equilateral triangle ,CD is the perpendicular bisector of AB Now. According to pythagoras theorem ,In△ACDAC 2 =AD 2 +CD 2 ⇒(2a) 2 =a 2 +( 3 ) 2 ⇒4a 2 −a 2 =3⇒3a 2 =3⇒a 2 =1⇒a= 1 =1cmHence , the length of the side of an equilateral triangle is 2 cm. Now, Perimeter of the triangle =(2+2+2)cm=6cm Hence perimeter of an equilateral triangle is 6 cm |
