The area of rectangles (including squares) is given by length x width.
for the square 20 x 20, its area is 20 x 20 = 400
For the rectangle 10 x 30, its area is 10 x 30 = 300
If the shapes are divided up into 10 x 10 squares, it can be seen that the square has four of them, where as the rectangle will only have three:

400 square feet (20 x 20 = 400)
1070 square feet is 154080 square inches. (1 square foot is 12x12 or 144 square inches.)a 20x20 inch tile is 400 square inches.So the question could be restated as "how many 400 square inch tiles does it take to cover 154080 square inches?"154080 / 400 = 385.2
Assuming your measurement is in feet - 400 square feet of timer.
25 of them, if I didn't break any.
20 x 20 = 400 The room has 400 square feet on the floor, 400 square feet on the ceiling, and (80 x height of the room) square feet on the walls.
400 (20x20) square inches is 2.78 square feet.
400
2.78 square feet.
400
If that is 20ft by 20ft then there are 400 square feet
400 square feet (20 x 20 = 400)
40
Yes. 20x20=400.
20 x 20 = 400 (square meters).
1070 square feet is 154080 square inches. (1 square foot is 12x12 or 144 square inches.)a 20x20 inch tile is 400 square inches.So the question could be restated as "how many 400 square inch tiles does it take to cover 154080 square inches?"154080 / 400 = 385.2
400 square feet. To calculate square feet simply multiply length by width - the result is the area in square feet.
