Question

A triangle has a perimeter 20.0 1 cm if its two sides are 6.38 cm and 5.0 67 cm find the third side Solution

Answer 1

Step-by-step explanation:

A triangle has a perimeter 20.0 1 cm if its two sides are 6.38 cm and 5.0 67 cm find the third side

Solution

Given :-

A triangle has a perimeter 20.0 1 cm

two sides are 6.38 cm and 5.0 67 cm

Find :-

Third Side of triangle

Step - by - Step - Explanation

Using Formula

★ Perimeter of triangle = Sum of all side .

So, Let

Third Side of triangle be x cm

Assume that, ∆ABC ,

Where,

AB = 6.38 cm

BC = 5.067 cm

CA = x cm

So,

==> perimeter of triangle = AB + BC + CA

==> 20.01 = 6.38 + 5.067 + x

==> 20.01 = 11.447 + x

==> x = 20.01 - 11.447

==> x = 8.563 cm

Hence

Third Side of triangle ∆ABC will be CA(x) = 8.563 cm
