Question

Find the area of a right-angled triangle whose base is 3 cm and height is 4 cm.​

Answer 1

Step-by-step explanation:

Given that:

Find the area of a right-angled triangle whose base is 3 cm and height is 4 cm.

To find: Area

Solution:

Area of right -angled triangle is given by

$= \frac{1}{2} \times base \times height \: (unit )^{2}$

Here

Base = 3 cm

Height = 4 cm

Area

$= \frac{1}{2} \times 3 \times 4 \: {cm}^{2} \\ \\ = 3 \times 2 \: {cm}^{2} \\ \\ = 6 \: {cm}^{2}$

Thus,

Area of right -angled triangle is 6 cm².

Answer 2

Answer: The answer is  6 cm².

Step-by-step explanation:

In the given question, we need to find the area of a right-angled triangle whose base is 3 cm and height is 4 cm.

We know,

Area of right -angled triangle is given by Pythagoras theorem

Area of triangle  = (1/2) * Base * height

Here,

Base = 3 cm

Height = 4 cm  

Therefore, Area of Triangle = (1/2) * 3 * 4

= 6 cm²

Hence, Area of right -angled triangle is 6 cm².
