length of either of the remaining equal sides is:​

Answer 1

Answer:

6cm

Step-by-step explanation:

15cm-3cm=12cm

12/2

6cm

Answer 2

Answer:

6 cm

Step-by-step explanation:

Base of isosceles triangle = 3 cm

Perimeter of triangle = 15 cm

Let the length of equal sides of triangle be x.

According to the question,

→ 3 + x + x = 15 cm

⇒ 2x = (15 – 3) cm

⇒ 2x = 12 cm

⇒ x = 12/2 cm

⇒ x = 6 cm

The length of either of the remaining equal sides are 6 cm.
