A gardner needs to fence a square garden. If the area of the garden is 1521 square metres, how long should the fence be?​

Answer 1

length of fence = 156 m

$\bf Area = 1521 m²$

Given that it is a square garden ,

$\boxed{\bf\pink{Area \: of \: square= a² }}$

$\bf a² = 1521$

$\bf a = √1521$

$\bf = 39 m$

length of fence will be equal to Perimeter of square

$\boxed{\bf\pink{Perimter \: of \: square = 4a }}$

$\bf \: perimeter \: = 4 \times 39$

$\bf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 156 \: m$
