Question

what is the length of diagnol of square if area is 361​

Answer 1

Answer:

Using the formulas:

A=a2

d=2a

Solving for d

d=2A=2·361=26.87006

Answer 2

Answer:

$area \: of \: square \: = {side}^{2}$

$361 = {s}^{2}$

$side = 19$

$all \: sides \: of \: square \: is \: equal$

$using \: the \: method \: of \: phyatagores \: method$

${h}^{2} = {19}^{2} + {19}^{2}$

${h}^{2} = 361 + 361$

${h}^{2} = 722$

$h = 26.87$
