Yes, using two 3ft x 3ft tiles.
yes.
It is: 7 times 3 = 21 square feet
7.5 square feet
3*8 = 24 square feet
Yes, using two 3ft x 3ft tiles.
To find the area of 3ft by 1ft, you multiply the two. So the area is 3 square feet.
yes.
66 square feet
Yes we can with the help of 2 tiles placed side-by-side.
You cannot. A 3ft x 3ft square has an area of 9 square feet. 9 does not divide 1200 evenly.
It is: 7 times 3 = 21 square feet
3ft
7.5 square feet
It depends on the shape. A 8ft-3ft-3ft triangle is impossible, a circle needs only one measure, a square only 1, a rectangle 2. Other quadrilaterals need more than 3. So the shape is indeterminate and, therefore, it is impossible to calculate the area.
A yard of Concrete is 3ft x 3ft x 3ft volume. It is usually poured over a 2" gravel sand mix for an additional four inches. So it should cover 36 "/4" = 9 (x 3ft x 3ft), or 81sq ft.The 'square feet' of area that it covers is 324/(depth of the concrete, in inches)
33 square yards
