Answer»

Given :

$\longmapsto\tt{Base=40\:cm}$

$\longmapsto\tt\boxed{Area\:of\:\triangle=\dfrac{1}{2}\times{b}\times{h}}$

$\longmapsto\tt{540=\dfrac{1}{{\cancel{2}}}\times{{\cancel{40}}}\times{h}}$

$\longmapsto\tt{540=20\:h}$

$\longmapsto\tt{h=\cancel\dfrac{540}{20}}$

$\longmapsto\tt\bf{h=27\:cm}$

So , The Height of Triangle is 27 cm ..

A triangle is a simple CLOSED curve figure made of three line SEGMENTS. It has three vertices , three SIDES and three angles .

Classification of Triangles based on Sides :

Classification of Triangles based on Angles :

If angle is less than 90 degree than the triangle is known as Acute Angled Triangle.
If an angle is of 90 degree then the triangle is known as Right Angled Triangle .
If the angle is GREATER than 90 degree than the triangle is known as Obtuse Angled Triangle .
