Question

∆PQR Draw a right angle triangle all its three vertices. Name the endpoint 'O'.
​

Answer 1

Answer:

The area is in the two-dimensional region and is measured in a square unit. It can be defined as the amount of space taken by the 2-dimensional object.

The area of a triangle can be calculated by 2 formulas:

area= \frac{a \times b }{2}

and

Heron’s formula i.e. area= \sqrt{s(s-a)(s-b)(s-c)},

Right Angle Triangle

Where, s is the semi perimeter and is calculated as s =\frac{a+b+c}{2} and a, b, c are the sides of a triangle.
