Question

find the area of triangle whose base is 20 cm and corresponding height is 12 cm​

Answer 1

Answer:

o==[]::::::::::::::::>120 CM is ur answer

Step-by-step explanation:

☜☆☞we know that area of triangle =1/2 X base X height

☜☆☞hence, given height =12CM and base =20cm

☜☆☞therefore area of triangle =1/2 X 20 X 12

☜☆☞ 120cm

Answer 2

AnswEr:-

Your Answer Is 120 cm².

ExplanaTion:-

Given:-

• Length of the Base of a triangle = 20 cm.

• The Length of corresponding height = 12 cm.

To Find:-

• The Area of the triangle.

Formula Used:-

$\bf\longrightarrow \boxed{ \bf A = \dfrac{1}{2} \times B \times H.}$

Where,

• A = Area of the triangle.

• B = Base of the triangle.

• H = Corresponding height of the triangle.

So Here,

• A = ?? [To Find].

• B = 20 cm.

• H = 12 cm.

Now,

By putting above values in the formula we get:-

$\tt\mapsto A = \dfrac{1}{2} \times B \times H.$

$\tt\mapsto A = \dfrac{1}{ \cancel 2} \times \cancel{20} \: cm \times 12 \: cm.$

$\tt\mapsto A = 10 \:cm \times 12 \: cm.$

$\bf\mapsto \boxed{ \bf A = 120 \: cm {}^{2} .}$

$\bf\therefore$ The Required Area Of The Triangle Is 120 Cm².

Related Formula:-

Here is one more formula to find out the area of any triangle whose height is not given but all three sides are given and this formula is commonly called as "Heron's Formula."

Which is,

$\tt\longrightarrow \boxed{ \bf A = \sqrt{s(s - a)(s - b)(s - c)}.}$

Where,

• s = Semi Perimeter of the triangle $\bf(i.e.\:\:Perimeter\times\dfrac{1}{2}).$

• a, b and c are the given three vertices or you can say three sides of the triangle.

So if any case we have given three sides of a triangle and we have to find out the area of that triangle than we can easily find it out by using Heron's Formula.
