Hey mate ,

Length of rectangle = 80 cm

Breadth of rectangle = 18 cm

Let it's diagonal be x cm

Since all angles of rectangle are 90°

Thus,

By applying Pythagoras Theorem

${hypotenuse}^{2} = {altitude}^{2} + {base}^{2}$

${x}^{2} = {(80)}^{2} + {(18)}^{2}$

${x}^{2} = 6400 + 324$

${x}^{2} = 6724$

$x = \sqrt{6724}$

$x = 82cm$

Thus , length of diagonal = 82cm.

HOPE YOU FIND IT HELPFUL !
