Question

two equal side of an isosceles triangle are each 2 cm more than t h r i c e the third side if the perimeter of triangle is 67 cm find the lengths of the sides​

Answer 1

Answer:

length of smaller side = 21 cm

length of each of the equal side  =23cm

Step-by-step explanation:

let the third side be x

length of each eaqual side = x + 2

perimeter = 2(x+2) + x

67 = 2(x+2) + x

⇒ 67 = 2x+4+x

⇒ 67 = 3x+4

⇒ 67-4 = 3x

⇒63/3 = x

⇒ x= 21 cm

length of smaller side = 21 cm

length of each of the equal side = 21+2 =23cm
