dont copy ​

Answer 1

Answer:

consider a right triangle

its hypotenuse = slant height , base = 5cm , height = 12cm

using pythagoras therom

hypotenuse square = $\sqrt{base^{2}+height^{2} }$

                              = $\sqrt{12^{2}+5^{2} }$

                              =$\sqrt{169}$

                              =13 cm

so slant height = 13cm
