The answer would be: 21w ft^2

Nathaniel Knight · Answer 2

The formula for area of a rectangle is length*width.

For this question,

width = w cm

length = 21 ft

The first step would be to get the length and width to be the same measurement.

1 ft = 30.48 cm

So you could change both into centimeters.

width = w cm

length = 21 * 30.48 = 640.08 cm

So the expression for the area of the floor would be:

w (640.08)
