Question

When each side of a square was reduced by 2 metres , it's area became 49square meter . What was the side of the first square ?

Answer 1

Assumption-

$\sf \: let \: the \: side \: of \: square \: be \: x$

$\sf \: Side \: of \: square \: after \: reducing = x - 2$

Now,

$\sf \: Area \: of \: square \: after \: reducing = 49$

$\sf (Side)² = 49$

$\sf (x - 2)² = (7)²$

$\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\: \sf (Side \:after \:reducing = (x-2))$

$\sf x - 2 = 7$

$\sf x = 7+2$

$\sf x= 9$

$\boxed{ \sf{Side\: of \; first\: square = 9m}}$
