Question

formula for length of a square

Answer 1

solution :-

given the area (A) =
$area \: = 65 \ \frac{1}{4} = \frac{261}{4} squre \: mtr \\ the \: wide \: = 5 \frac{1}{16} = \frac{81}{16} mtr \\ length = \frac{area}{wide} \\ length = \frac{ \frac{261}{4} }{ \frac{81}{16} } \\ length = \frac{16 \times 261}{81 \times 4} \\ length = \frac{4176}{336} \\ length = \frac{87}{7}mtr \\ length = 12 \frac{3}{7}$
