Answer 2

Given:-

• Sides of a triangle are 80 m, 78 m, and 61 m.

⠀

To find:-

• Perimeter of a triangle.

⠀

Solution:-

★ In this question we have given the three sides of a triangle. We have to find out the perimeter of a triangle. Let's do it.

⠀

Here,

• a = 80 m
• b = 78 m
• c = 61 m

⠀

According to the question,

⠀

⇢ P = a + b + c

⇢ P = 80 + 78 + 61

⇢ P = 158 + 61

⇢ P = 219 m

⠀

Hence,

• The Perimeter of a triangle is 219 m.

⠀

Therefore,

• Option (a) is correct.
