Question :-

  • A Triangle has an Area of 48 cm² . The Height of the Triangle is 6 cm . What is the Base of the Triangle ?

Answer :-

  • Base of Triangle is 16 cm .

Explanation :-

As per the provided information in the given question, we have been given that the Area of Triangle is 48 cm² . It's Height is given as 6 cm . And, we have been asked to calculate the Base of Triangle .

For calculating the Base of Triangle , we will use the Formula :-


\bigstar \: \: \: \boxed{ \sf{ \: Area \: _(Triangle) \: = \: (1)/(2) \: * \: B \: * \: H \: }}

Where ,

  • B denotes to the Base .
  • H denotes to the Height .

Therefore , by Substituting the given values in the above Formula :-


\dag \: \: \: \sf { Area \: _(Triangle) \: = \: (1)/(2) \: * \: Base \: * \: Height }


\longmapsto \: \: \: \sf {48 \: = \: \frac {1}{2} \: * \: Base \: * \: 6 }


\longmapsto \: \: \: \sf {48 \: * \: 2 \: = \: 1 \: * \: Base \: * \: 6}


\longmapsto \: \: \: \sf {96 \: = \: 1 \: * \: Base \: * \: 6}


\longmapsto \: \: \: \sf {96 \: = \: 6 \: * \: Base }


\longmapsto \: \: \: \sf {Base \: = \: \frac {96}{6} }


\longmapsto \: \: \: \textbf {\textsf {Base \: = \: 16 \: cm}}

Hence :-

  • Base of Triangle = 16 cm .

Question : -

A triangle has an area of 48 square centimetres. The height of the triangle is 6 centimetres. What is the base of the triangle ?

Given : -

  • Area of triangle = 48 cm²

  • Height of triangle = 6 cm

To Find : -

  • Base of triangle

Formula Used : -


\blue{\boxed{Area \: of \: triangle = (1)/(2) * b * h}}

Where ,

  • b = Base of triangle

  • h = Height of triangle

Concept : -

In this question the concept belongs to the areas of two dimensional shapes i.e. how we can find length , breadth or height with the help of given area .

So let's get started : -


\longmapsto \: 48 = (1)/(2) * b * 6

Now , transposing 2 to left hand side :


\longmapsto \: 48 * 2 = 1 * b * 6

Now , multiplying 48 with 2 and multiplying b with 1 and 6 :


\longmapsto \: 96 = 6b

Now , transposing 6 to left hand side :


\longmapsto \: \cancel(96)/(6) = b

Now , by cancelling them we get :


\longmapsto \: \red{ \boxed{ \sf{b = 16 \: cm}}}

  • Therefore , base of triangle is of 16 cm

Verifying : -

We know that area of triangle is equal to 48 cm². So :


\rightarrow \: (1)/( \cancel2) * \cancel{16} * 6 = 48

Now , by cancelling 16 with 2 we get :


\rightarrow \: 8 * 6 = 48

So , by multiplying we get :


\rightarrow \: 48 = 48

That means :


\rightarrow \: L.H.S = R.H.S

  • Hence , Verified .

Therefore, our answer is valid .
