-20
it would be:
[(40+d)2+(20+d)2]-80
to completely solve it, I would need to know d.
by the way, this was answered by a 12-year old girl.
4d squared +120d ft squared squared = the number 2
28 ft X 22ft equals total sq. ft of total areas
20 x 14 equals pool area.
Subtract the second from the first number gives you the area of the deck.
800sq'
Valerie is installing a 20ft by 12ft swimming pool surrounded by a 6ft deck. What is the total area of the deck?
3.28084 ft = 1 meter 20 ft = (20 / 3.28084) = 6.096 meters 40 ft = (40 / 3.28084) = 12.192 meters 20ft by 40ft = 6.096 m by 12.192 m. This is what you asked for. You didn't ask for the area of a plot measuring 20ft by 40ft. If you wanted the area, you would have had to: -- ask for "square meters" -- guarantee that the plot is rectangular, i.e. the corners are right angles
The area of a room 40ft by 40ft = 1,600 square feet.
Area of deck = (20+2d)x(40+2d)-(20x40) Area of deck = (20x40)+40d+80d+4d2 -(20x40) Area of deck = 120d+4d2
The AREA of a circle that has a radius of 40ft is 5026.54825 square feet
The area is 120ft2
The area is 314.159 square feet.

You can't have cubic feet in an area. Area is for two dimentions and volume is for 3 dimentions.20ft by 20ft is 400ft2
A dump truck load of 7.5 yards
Area=length times width 90 times 40 = 3,600 feet
Assuming the shape is an irregular octagon (since there are 8 lengths given), there is not enough information to answer the question. Polygons with more than three sides are not rigid. They can be flexed so that their shape and area changes without changing their side lengths. As an illustration, think of a square that can be flexed to form a rhombus and that can be made as thin as you like, with an area approaching zero.
