Question 938243
The length of the diagonal in quadrilateral A is {{{5sqrt(3) }}}
the length of the diagonal in quadrilateral B is {{{8sqrt (2)}}}
The length of the diagonal in quadrilateral C is {{{3sqrt(12)}}}

{{{3sqrt(12)}}}->you can simplify this one:
{{{3sqrt(4*3)}}}=>{{{3sqrt(2^2*3)}}}=>{{{3*2sqrt(3)}}} =>{{{6sqrt(3)}}}

What is the approximate sum of the lengths of the diagonals of quadrilaterals A,B, and C?

{{{5sqrt(3) +8sqrt (2)+6sqrt(3)}}}

{{{11sqrt(3) +8sqrt (2)}}} .....since {{{sqrt(3)=1.732050807568877}}} rounded {{{sqrt(3)=1.73}}} and {{{sqrt (2)=1.414213562373095}}} rounded {{{sqrt (2)=1.41}}}, then

{{{11*1.73 +8*1.41}}} .

{{{19.03 +11.28}}}

{{{30.31}}}-> your answer: the approximate sum of the lengths of the diagonals of quadrilaterals A,B, and C

ps:

when you need to type radicals here, type it this way:

three of these brackets {
then sqrt(a) 

then close with three of these brackets }

if you need for example fourth root, you do it this way:

three of these brackets {
then root(4,a) 
then close with three of these brackets }
