area = length x width area = 90 feet 10 feet x 9 feet = 90 square feet.
To determine how many patio stones are needed, first convert the dimensions of one stone from inches to square feet. A 24-inch by 24-inch stone is 2 feet by 2 feet, giving it an area of 4 square feet. Dividing the total patio area of 480 square feet by the area of one stone (4 square feet) results in 120 stones needed for the patio.
AREA = LENGTH x WIDTH LENGTH = 2 X WIDTH AREA = 2 x WIDTH X WIDTH = 900 900/2 = WIDTH X WIDTH 450 = WIDTH X WIDTH = WIDTH SQUARED WIDTH = SQUARE ROOT (450) = 21.21 FEET LENGTH = 42.42 FEET

Area of a Square = Length*Length = 3*3 = 9 square feet.
area = length x width area = 90 feet 10 feet x 9 feet = 90 square feet.

200 square feet. To calculate square feet simply multiply length by width - the result is the area in square feet.
225 square feet
To determine the amount of decking square feet needed for the outdoor patio renovation project, measure the length and width of the patio area in feet and multiply the two dimensions together to calculate the total square footage required.

You don't measure the length and width in square feet. Square feet is an area. You measure the length and width in feet, then multiply them to get the area in square feet.
To calculate how many 4x8 pavers are needed for a 10x12 patio, first find the area of the patio: 10 feet x 12 feet = 120 square feet. Next, calculate the area of one paver: 4 feet x 8 feet = 32 square feet. Finally, divide the patio area by the paver area: 120 square feet ÷ 32 square feet = 3.75. Since you can't have a fraction of a paver, you'll need 4 pavers to cover the patio completely.
