Question

find the area of right angle triangle whose base is 3 cm perpendicular to centimetre and hypotenuse is 5 cm​

Answer 1

Answer:

Step-by-step explanation:triangle ABC

AB=3CM

AC=5CM

a*2+b*2=c*2

c*2-b*2=a*2

25-9=16

4×4=16

So answer is 4

Answer 2

The area of right angle triangle is 6 cm².

Step-by-step explanation:

Given : Triangle whose base is 3 cm perpendicular to centimeter and hypotenuse is 5 cm​.

To find : The area of right angle triangle ?

Solution :

The base of the triangle is b=3 cm

The hypotenuse of the triangle is h=5 cm

Applying Pythagoras theorem,

$h^2=p^2+b^2$

Substitute the value,

$5^2=p^2+3^2$

$25=p^2+9$

$p^2=25-9$

$p^2=16$

$p=4$

The perpendicular is 4 cm.

The height of the right angle triangle is 4 cm.

The area of the triangle is $A=\frac{1}{2}\times \text{base}\times \text{height}$

$A=\frac{1}{2}\times 3\times 4$

$A=3\times 2$

$A=6\ cm^2$

The area of right angle triangle is 6 cm².
