Question

3. Find the missing values:
Base=40 cm
Height=?
Area of triangle=540 cm²​

Answer 1

Given :

• Area of Triangle is 540 cm² .
• Base of Triangle is 40 cm .

To Find :

• Height of Triangle .

Solution :

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

Using Formula :

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

Putting Values :

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

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

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

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

So , The Height of Triangle is 27 cm ..

Triangle :

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 :

• A triangle having three unequal sides is called as Scalene Triangle.
• A triangle having two equal sides is called as Isosceles Triangle .
• A triangle having three equal sides is called as Equilateral Triangle .

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 .
