Question 1195450


If {{{L=M^2}}} 

 what is the percentage increase in {{{L}}} if{{{ M}}} increases by {{{10}}}%?

if {{{M}}} increases by {{{10}}}%, we have{{{ M+0.10M}}}


{{{ L=(M+0.10M)^2 }}}

{{{ L=(1.10M)^2 }}}

{{{L=1.21M^2}}} or

{{{L=(121/100)M^2}}}


{{{(121/100)= 121}}}%=>{{{100}}}%+{{{21}}}%

the percentage increase in {{{L }}}is {{{21}}}%
