Question 1151194

The side length of square {{{A}}} is {{{36cm}}}.

the area of square {{{A}}} is {{{(36cm)^2=1296cm^2}}}

 The side length of square {{{B}}} is {{{42cm}}}. 

the area of square {{{B}}} is {{{(42cm)^2=1764cm^2}}}

 the ratio of the area of square {{{A}}} to the area of square {{{B}}} is:

{{{A/B=1296cm^2/1764cm^2}}}

{{{A/B=1296/1764}}}

{{{A/B=36/49}}}=> answer
