The picture of the small one has a number 42m and the larger one has a number 57m.

Can someone please help me my possible answers aer, 576m^2, 3,249m^2, 3,181m^2, or 14m^2

**Reiny**, Saturday, April 7, 2012 at 10:59pmI will assume that the values of 42 m and 57 m are corresponding sides.

Areas of similar shapes are proportional to the square of their corresponding sides

A/564 = 57^2/42^2

A = 564(3249)/1764 = appr 1039 m^2

According to my assumption, none of the given answers match.

check: √(1039/564) = 1.357...

57/42 = 1.357...

my answer is correct.
