Answer:
the sides are of length 3 cm , 3cm , and 5 cm
Step-by-step explanation:
let the congruent side be x.
therefore perimeter = x + x + (x+2) = 3x + 2 = 14cm (given)
so we get the equation 3x+2 = 14
⇒ 3x = 14 - 2 = 12.
∴ x = 12 ÷ 4 = 3
therefore the sides are of length 3 cm , 3cm , and 3 + 2 = 5 cm
