Answer:
22 cm
Step-by-step explanation:
let the ∆be ∆abc.
2 sides of a perpendicular ∆= 5cm and 12 cm
therefore, generally the longest side is base
therefore, here 12 is big than 5
so, 12 cm is the measurement of base= bc= 12 cm
therefore, ab= 5cm
so by this the other side of triangle should be 5 too
by this 5+5+12= 10+12=22
=22 cm is the correct ans. for this
but you've given the different options
I hope it's helpful for you
