What is the area(in cm2) of this triangle?__

Question

What is the area(in

{c m}^{2}

) of this triangle?
___

Answer:
:

(Area of triangle)

= \frac{1}{2} \times base \times height

The three sides are

(10cm, 6cm and 8cm)

10^{2} = 6^{2} + 8^{2}

The sides satisfy Pythagoras theorem. Hence, this is a right-angled triangle, with the sides

6cm

and

8cm

being the base and the height, respectively.
Hence,

A r e a = \frac{1}{2} \times 6 \times 8

{c m}^{2}

= 24 c m^{2}
