Question

The nose of the origami dog is a right angle with sides that are 2 cm, 3 cm, and 3.6 cm long. What is the area of this triangle?

Answer 1

Given:

The sides of a right triangle are 2 cm, 3 cm, and 3.6 cm.

To find:

The area of the right triangle.

Solution:

Area of a triangle is:

$Area=\dfrac{1}{2}\times base\times height$

In the given triangle 3.6 cm is the largest side, it means 3.6 cm is the length of the hypotenuse. So, 2 cm and 3 cm and the base and height of the triangle.

Now, the area of the given triangle is:

$Area=\dfrac{1}{2}\times 2\times 3$

$Area=3$

Therefore, the area of the given triangle is 3 square cm.
