Question

Diagonal of a rectangle is 13 cm length is 12 cm find its Breadth

Answer 1

Given length ( l ) = 12 cm

Diagonal ( d ) = 13 cm

Let breadth = b cm

b² = d² - l²

=> b² = 13² - 12²

=> b² = ( 13 + 12 )( 13 - 12 )

=> b² = 25

=> b = √25

=> b = 5 cm

Answer 2

Let the width of the triangle be "x"

By Pythagorean theorem

(13) ^2=(12) ^2+x^2

169=144+x^2

169-144=x^2

25=x^2

x=√25

x=5

Therefore width=5
