Question 1063562
A width and a length multiplied together will give you the area.
x*4x=4x^2, and that equals 68 m^2
divide by 4 and x^2=17 m^2
x=sqrt(17)=4.1 m
4x=16.4 m
Those are the dimensions, width by convention being the shorter and length being the longer.
4.1*16.4=67.24 m^2, a little smaller because we rounded down.
