Question

The length and breadth of a rectangle are 16cm and 12cm. Find its diagonal.

Answer 1

Answer:

20cm

Step-by-step explanation:

the diagonal can be find using pythagoras theorem.

AC^2 = AB^2 + BC^2

= 16^2 + 12^2

= 256 + 144

= 400

AC = 20 cm

diagonal = 20cm

Answer 2

Step-by-step explanation:

GIVEN,

LENGTH = 16CM

BREADTH =18 CM

WE KNOW THAT DIAGONAL OF RECTANGLE =

$\sqrt{l \: } \: {}^{2} \: + \sqrt{b {}^{2} }$

SO HERE,

ROOT 16 + ROOT 18

$\sqrt{400 \: \: } \: \: = 20$

THEREFORE, DIAGONAL OF THE RECTANGLE IS 20 CM.
