Find the perimeter of an isosceles traingle whose equal sides are 15 cm and remaning sind is 23 cm
Answers
Answer:
- The perimeter of an isosceles triangle is 53 cm.
Step-by-step explanation:
Given that:
An isosceles triangle having,
- Equal sides = 15 cm
- Other side = 23 cm
To Find:
- The perimeter of an isosceles traingle.
Formula used:
- Perimeter of an isosceles triangle = (2 × Equal sides) + Other sides
Finding the perimeter of an isosceles traingle:
⟶ Perimeter = (2 × 15) + 23
⟶ Perimeter = 30 + 23
⟶ Perimeter = 53
∴ Perimeter of an isosceles triangle = 53 cm
Perimeter of isosceles triangle = sum of all sides
= 15cm + 15cm + 23cm
= 53cm
Or
You also apply this formula 2a + b to find the perimeter of isosceles triangle.
Perimeter of isosceles triangle = 2a + b
= 2 × 15cm + 23cm
= 30cm + 23cm
= 53cm
