Length = 18 m 72 cm
Breadth = 13 m 20 cm
Area= (1800+73)cm × (1300+20)cm.
= 1873×1320 = 2472360 square cm
now we know area of square= 4× a square( where a is the side of square)..
4 a square= 2472360
=a square= 618090
= a = √618090....
then divide area of rectangle by area of square..... hope u find it useful..
