Question

the area of a square is equal to area of rectangle whose length is 16 centimetre and breadth is 9 cm find the perimeter of a squ
$area \: of \: a \: square = area \: of \: a \: rectangle \\ ( {side) }^{2} = length \times breadth \\ ( {side)}^{2} = 16 \times 9 \\ ( {side)}^{2} = 144 \\ side = \sqrt{144 } \\ side = 12 \\ perimeter \: of \: a \: square = 4 \times side \\ 4 \times 12 \\ = 48$
​

Answer 1

Answer:

given;

l=16cm

b=9cm

therefore

. perimeter of square=

$2(l + b)$

=2 ×25cm

=50cm
