Question

If 2 perpendicular sides of a right-angle triangle are 5 cm and 12 cm, its perimeter is

Answer 1

Answer:

22cm

Step-by-step explanation:

5+5+12 cm since all 3 angles equal to perimeter

Answer 2

Answer:

30

Step-by-step explanation:

a right angle triangle has 3 sides and always followed by Pythagoras theorem.

H^2=B^2+P^2

B=base, P=perpendicular, H=hypotenuse

in that question B=5

P=12

from Pythagoras theorem

25+144=169

H^2=169

H must be 13.

perimeter of a triangle is H+B+P

5+12+13=30

perimeter of that triangle is 30.
