Question

If area of a triangle is 30cm²,base=3cm find its height​

Answer 1

Answer:

20

Step-by-step explanation:

area of triangle= base*height/2

Answer 2

Answer:

The height of the triangle is 20 cm

Step-by-step explanation:

Given :

Area of the triangle = 30 cm²

Base of the triangle = 3 cm

To find :

The height of the triangle

Taken :

To find the height of the triangle use this formula :

$\boxed{\sf{h_{b}=2\dfrac{A}{b}}}$

Where,

A = Area of the triangle

b = Base of the triangle

Solution :

$\longrightarrow\sf{h_{b}=2\times\dfrac{{30cm}^{2}}{3cm}}$

$\longrightarrow\sf{h_{b}=\dfrac{\cancel{60cm}}{\cancel{3cm}}}$

$\longrightarrow\sf{h_{b}=20cm}$

So , the height of the triangle is 20 cm
