Question

2. The base and hypotenuse of a right angled triangle are respectively 6 and 10 long find its area cm
​

Answer 1

Answer:

b=6

h=10

Area=

$\qquad\sf{:}\longrightarrow 1/2×6×10$

$\qquad\sf{:}\longrightarrow 60/2$

$\qquad\sf{:}\longrightarrow 30units^2$

Answer 2

Answer:

Let ABC is a right angled triangle at B

Base=BC=6cm

HypotenuseAC=10cm

Using Pythagoras theorem,

AC

=8cm

Altitude=AB=8 cm

Now , Area of triangle =
