Question

The length and breadth of rectangle is 12m and 5m. Find the length of its diagonal.

Answer 1

Answer:

13m

Step-by-step explanation:

Length =12m

Breadth = 5m

As it is a rectangle, the angles are 90 degree

According to pythagoras theorem

Diagonal squared = base squared + perpendicular squared

Diagonal square = 12^2+5^2

Diagonal ^2 =  144+25

Duagonal^2 =169

Diagonal = 169 square root

Diagonal =13m

Answer 2

$Diagonal \: = \sqrt{ {l}^{2} + {b}^{2} } \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \sqrt{ {12}^{2} + {5}^{2} } \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \sqrt{144 + 25} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \sqrt{169} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 13m$
