24964 students are to be sit in a hall in such a way that each row contains as many students as the number of rows. Find the number of rows and the number of student in each row. please answer it fast it is urgent..

Answer»

$Let \: the \: number \: rows = x$

$Number \:of \: students \:sit \: in \:each \:row = x$

$Number \:of \: Students \:sit\:in \:the \:hall$

$= 24964\: \blue{ ( given )}$

$\implies x \times x = 24964$

$\implies x^{2} = 2^{2} \times 79^{2}$

$\implies x = \sqrt{ 2^{2} \times 79^{2}}$

$\implies x = 2 \times 79$

$\implies x = 158$

THEREFORE.,

$\red{the \: number \: rows\:in \:the \:hall}\green {= 158}$

$\red{Number \:of \: students \:sit \: in \:each \:row}$

$\green { = 158}$

13.

a square and rectangle have the same perimeter. calculate the area of the rectangle if the side of square is 40 cm and the length of the rectangle is 60 using formula of mensuration

Answer»

ANSWER:

Step-by-step explanation:

side of SQUARE = 40 cm

perimeter of the square=(4*40) cm=160 cm

let the breadth of the rectangle be x cm

length of rectangle = 60 cm

as the perimeter of the rectangle = perimeter of the square,

according to the problem,

2*(x+60)=160

or 2x+120=160

or 2x=160-120

or 2x=40

or x=20.

therefore ,

AREA of rectangle =( 20*60) cm.sq.=1200 cm.sq. (ans)
