Answer 1

• Question

Is it possible to have a triangle with sides 4 cm,3 cm and 5 cm.

• Answer

True

Explanation - The sides of triangle can have different measures. Such a triangle is called Scalene triangle.

A scalene triangle is the one in which all sides are unequal.

• Know more -

$\blue{\bigstar}$There three types of triangle -

• Equilateral triangle
• Isosceles triangle
• Scalene triangle 

$\blue{\bigstar}$Equilateral triangle -

• In this all three sides are equal.

• Area of equilateral triangle -

↬ $\sf{\dfrac{\sqrt{3}}{4}a^2}$

• Perimeter of equilateral triangle -

↬ 3a

where,

a = side of triangle

$\blue{\bigstar}$Isosceles  triangle -

• In this two sides of triangle are equal.

• Area of isosceles triangle -

↬ $\sf{\dfrac{1}{2} \times base \times height}$

• Perimeter of isosceles triangle -

↬ 2a + b

$\blue{\bigstar}$Scalene triangle -

• In this no side is equal.

• Area of scalene triangle -

↬ Heron's formula = $\sf{\sqrt{s(s - a)(s - b)(s - c)}}$

• Perimeter of scalene triangle -

↬ Perimeter = Sum of all three sides
