Question

Find the perimeter of a triangle each of whose sides is 14 cm long

Answer 1

☆ Solution ☆

Given :-

• Side = 14 cm

To Find :-

• The perimeter of triangle.

Step-by-Step-Explaination :-

As we know that :-

Perimeter of triangle = 3 × sides

Putting the respective value

Perimeter of triangle = 3 × 14

Perimeter of triangle = 42

Hence,

Perimeter of triangle = 42 cm .

____________________________

Know More :-

Perimeter of Rectangle = 2 ( l + b )

Perimeter of Square = 4 × side

Perimeter of Triangle = 3 × side

Area of Rectangle = L × B

Area of Square = ( side ) ²

Area of Rhombus = Product of Diagonal/2.

Area of Parallelogram = Base × Height.

Area of triangle = 1/2 × base × height

Answer 2

Given:-

• Side = 14 cm

To Find :-

• Perimeter of triangle.

As we know that :-

$\purple{\boxed{\sf{Perimeter_{(triangle)}\ =\ 3\:×\: side}}}$

= 3 × 14

= 42

Hence,

Perimeter of triangle = 42 cm.

$\sf{Area\;of\;Rectangle\;=\;Length\;\times\;Breadth}$⠀

$\sf{Area\;of\;Square\;=\;(Side)^{2}}$

$\sf{Area\;of\;Triangle\;=\;\dfrac{1}{2}\;\times\;Base\;\times\;Height}$⠀

$\sf{Area\;of\;Parallelogram\;=\;Base\;\times\;Height}$⠀

$\sf{Area\;of\;Circle\;=\;\pi r^{2}}$

$\sf{Perimeter\;of\;Rectangle\;=\;2\;\times\;(Length\;+\;Breadth)}$⠀

$\sf{Perimeter\;of\; Square\;=\;4\;\times\;(Side)}$⠀

$\sf{Perimeter\;of\;Circle\;=\:2\pi r}$
