The area of a square is 36 Sq ft. if each side is lengthened by four feet. how could the perimeter of the new square be xalculated

Area of a square=length times lenght or legnth^2

area=36 so legnth=√36=6

perimiter of square=legnth times 4 since all sides are same legnth

if each side legnthened by 4 feet then

original premiter=4 times 6=24

new perimiter=4 times (6+4) = 4 times (10) = 40

the new perimiter is 40 ft
