Question

Find the areas of the traingles Whose base and height are guven below . base=8 cm height=9 cm​

Answer 1

Answer:

given Base = 8 cm

Height = 9cm

Area of Triangle = 1/2 × base × height

= 1/ 2 × 8 × 9 cm

= 36 cm

Answer 2

Given :

• Base of Triangle is 8 cm .
• Height of Triangle is 9 cm .

To Find :

• Area of Triangle .

Solution :

$\longmapsto\tt{Base=8\:cm}$

$\longmapsto\tt{Height=9\:cm}$

Using Formula :

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

Putting Values :

$\longmapsto\tt{\dfrac{1}{{\cancel{2}}}\times{{\cancel{8}}}\times{9}}$

$\longmapsto\tt{4\times{9}}$

$\longmapsto\tt\bf{36\:{cm}^{2}}$

So , The Area of Triangle is 36 cm² ...

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 .
