Question

find the perimeter of right angled triangle,whose two legs are 3cm,4cm and hypotenuse is 5 cm​

Answer 1

Step-by-step explanation:

$P = a + b \sqrt{ {a}^{2} + {b}^{2} }$

$= 3 + 4 \sqrt{ {3}^{2} + {4}^{2} }$

$= 12cm$

Answer 2

Given Data :

Two sides of a triangle = 3 cm and cm

Hypo = 5 cm

To find :

It's Perimeter

Formula :

Perimeter = a + b + c

Solving problem :

a = 3 cm

b = 4 cm

c = 5 cm

Perimeter = a + b + c

= 3 + 4 + 5

= 7 + 5

= 12 cm

The perimeter of the triangle = 12 cm
