Question

The dimension of a given rectangular tiles are 12 cm ×16 cm.Find the length of its diagonal?(the chapter is square and square root )

Answer 1

L=12
B=16
diagonal =under root L square+ B square
12^2+16^2
144+256
400
underroot400=20

Answer 2

Hlo friend.. Cutiepie Here..

Here is ur answer :

Length l of Rectangular tiles = 12 cm

Breadth b of Rectangular tiles = 16 cm.

To find, Diagonal D of Rectangular tiles

Diagonal D =
$\sqrt{ {l}^{2} + {b}^{2} }$


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


$= \sqrt{144 + 256}$


$= \sqrt{400}$

$= 20$



Diagonal D of Rectangular tiles = 20 cm


HOPE IT HELPS YOU .
