Question

if the Diognal of the rectangle is 20m and lenght is 16 what is the Breath of rectangle​

Answer 1

Answer:

12cm

Step-by-step explanation:

20^2=   16^2+breath^2

400=256+breath^2

400-256=breath^2

squareroot of 144= breath

breath =12cm

Answer 2

Diagonal= 20m

length= 16m

breadth= xm

$diagonal = \sqrt{ {(length)}^{2} - ( {bredth)}^{2} }$

on substituting-:

$20m = \sqrt{( {16)}^{2} - ( {x)}^{2} }$

$on \: squaring \: on \: both \: the \: sides \\ \\ \\ 400 = {16 }^{2} - {x}^{2} \\ 400 = 256 - x {}^{2} \\ 400 - 256 = {x }^{2} \\ 144 = {x }^{2} \\ x = \sqrt{144 } \\ therefore \: x = 12m$
