Question

the base for a triangle is 4.6 and the length is 2.5 What is the area

Answer 1

Triangle

Solve for area

A=5.75

b Base

4.6

hb Height

2.5

Unit Conversion:

Solution

A=hbb

2=2.5·4.6

2=5.75

Answer 2

Answer:

Area of the triangle = 5.75 cm²

Step-by-step explanation:

Given :

Base of the triangle = 4.6 cm

Lenght or height of the triangle = 2.5 cm

(Taken , "cm" there is not given anything)

To find :

The area of the triangle

Taken :

To find the area of the triangle use this formula -:

$\boxed{\tt{A=\dfrac{1}{2}\times\:b\times\:h}}$

Where,

A = Area of the triangle

b = Base

h = Height

Solution :

$:\Rightarrow\tt{A=\dfrac{1}{\cancel{2}}\times\cancel{4.6}\times2.5}$

$:\Rightarrow\tt{A=2.3\times2.5}$

$:\Rightarrow\tt{A=5.75{cm}^{2}}$

So , the area of the triangle is 5.75 cm² .

Extra information :

If the length of each side of the triangle will be given use the Heron method to find the area of the triangle -:

First ,

$\boxed{\rm{s=\dfrac{a+b+c}{2}}}$

Where,

a , b and c are the length of each side of the triangle

And s is the semi perimeter of the triangle

After that -:

$\boxed{\rm{A=\sqrt{s(s-a)(s-b)(s-c)}}}$

So , after using this formula we will get the area of the triangle
