Arectangle has an area of 48 in square every dimension of the rectangle is multiplied by a scale factor and the new rectangle has an area of 12 inches square what is the scale factor

Area of a rectangle is width time length so A = w*l

we know that 48 = w*l and than we multiplied every dimensions of the rectangle by a scale factor x so  w*l*x the new area will be equal 12 inches square 

w*l=48
x*w*l = 12

x*48=12

x = 12/48 = 1/4 

so than result that this scale factor is equal 1/4
