I assume you mean a diameter of 3 feet. Divide the diameter by 2, to get the radius. Then use the standard equation for the area of a circle:
area = π x radius^2 = π x (3 ft ÷ 2)^2 = 9/4 π sq ft ≈ 7.07 sq ft
What is the circumference of a circle 3ft
A circle with a radius of 135 units has an area of 57,255.53 square units.
A rectangle is a two dimensional object, with length and width but not height. An object with length, width and height could be a cuboid, in which case is it still the area that is required or the volume?
Yes, using two 3ft x 3ft tiles.
(2 x 3 + 2 x 3 + 3 x 3) times 2 ie (6 + 6 + 9) x 2 = 42ft2
What is the circumference of a circle 3ft
A circle with a radius of 135 units has an area of 57,255.53 square units.
Radius is x2 so area is x4.
Area = pi*1.52 = 7.069 square feet rounded to 3 dp
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.

Because Area and Perimeter are not directly linked. If you were to make the fence into a triangle you would get another area, a circle would give a fourth.

Yes, using two 3ft x 3ft tiles.
To find the area of a rectangle, you multiply the length by the width. In this case, the length is 10 feet and the width is 3 feet. Therefore, the area of a 10ft by 3ft rectangle is 10 feet x 3 feet = 30 square feet.
To find the area of 3ft by 1ft, you multiply the two. So the area is 3 square feet.
(2 x 3 + 2 x 3 + 3 x 3) times 2 ie (6 + 6 + 9) x 2 = 42ft2
