Question

And the length ay diagonal of the rectangle whose side are
16 cm and 12 cm​

Answer 1

Step-by-step explanation:

16 +16 = 32

12 +12 = 24

32 + 24 = 56

Answer 2

formula for diagonal (d) of rectangle is given below.

$diagonal = \sqrt{( {l}^{2} + {w}^{2} ) }$

where l is length of the rectangle and w is width of the rectangle .

l = 16cm and w = 12cm

$d= \sqrt{( {16}^{2} + {12}^{2} ) }$

$d = \sqrt{256 + 144}$

$d = \sqrt{400}$

$d = 20cm$
