Question

The perimeter of a tringle is 67 cm if two sides measure 23 cm and 10 cm , find the third side.​

Answer 1

$\huge{\bold{\underline{Solution:-}}}$

Given:-

Perimeter of the Triangle = 67cm

And , Two sides of a triangle = 23cm ,10cm

We know that;

Perimeter of the Triangle = a + b + c

$\implies$ 67 cm = 23+10+c

$\implies$ 67 cm = 43 + c

$\implies$ c = 67 - 43

$\implies$ c = 24cm✔️

$\implies$ The Third side of the Triangle = 24cm.

Sᴏʟᴜᴛɪᴏɴ:

Given:-

Perimeter of the Triangle = 67cm

And , Two sides of a triangle = 23cm ,10cm

We know that;

Perimeter of the Triangle = a + b + c

⟹ 67 cm = 23+10+c

⟹ 67 cm = 43 + c

⟹ c = 67 - 43

⟹ c = 24cm

➽The Third side of the Triangle = 24cm
