Question

Find the length of the hypotenuse of a right triangle,the other two sides of which measure 9cm and 12 cm

Answer 1

....................................

Answer 2

formula is
$h ^{2} = p ^{2} + {b}^{2}$
h=?
p=12cm
b=9cm

A.T.Q

h=
$\sqrt{9^{2} + {12}^{2} }$
$= \sqrt{81 + 144}$
$= \sqrt{225}$
$= 15$
hence, hypotenuse = 15 cm
