Question 1035403
Hi there,
Area of rectangle = length x breadth
Area = 13.6 x 3.4
Area = 46.24 m^2
Area of square = length x breadth
(as breadth and length are the same size 
in a square)
Side length ^2 = Area
Side length ^2 = 46.24
Side length = √46.24
Side length = 6.8 meters.
Hope this helps :-)
