Question

Around a square pool,there is a footpath of width 2m. If the area of the footpath is 7/9 times that of pool find the area of pool

Answer 1

THEREFORE,
$(x - 12)(7x + 12) = 0$

$(x - 12)=0\:or(7x + 12)=0$

$x = 12 \: or \: x = \frac{ - 12}{7}$

BUT,
$x = \frac{ - 12}{7} \: is \: not \:acceptable$
$x = 12$


THEREFORE,
THE LENGTH OF THE SQUARE POOL IS 12m

THUS,
THE AREA OF SQUARE POOL

$= {12}^{2} = 144 {cm}^{2}$
FINAL ANSWER:
THE AREA OF SQUARE POOL IS 144 sq .cm.
