320 ft2
Simply multiply 16 times 20. Area is always Length times width (assuming you are talking about a rectangle).
There are: 16*20 = 320 square feet
16 x 16.5 square feet
If the big square is 20 ft on each side the perimeter is 4*20 = 80 ft. The small square is one-fifth of the bigger square so each side will be 20/5 = 4 ft. The small square perimeter will be 4*4 = 16 ft. Combined perimeter = 80 +16 = 96 ft.
15*16 = 240 square feet.
16 ft * 24 ft = 384 ft2
There are: 16*20 = 320 square feet
11 * 16 = 176 square feet
20 ft x 20 ft = 400 square ft
16 x 16.5 square feet
Perimeter of [ 16 x 26 ] rectangle = 16 + 16 + 26 + 26 = 84-ft . Perimeter of a 20-ft square = 4 x 20 = 80-ft . The rectangle has the greater perimeter.
The answer depends on the units used for 16 and 20. It should be blindingly obvious to anybody that 16 ft x 20 ft and 16 cm x 20 cm, for example, will give very different answers.
If the big square is 20 ft on each side the perimeter is 4*20 = 80 ft. The small square is one-fifth of the bigger square so each side will be 20/5 = 4 ft. The small square perimeter will be 4*4 = 16 ft. Combined perimeter = 80 +16 = 96 ft.
15*16 = 240 square feet.
16 ft * 24 ft = 384 ft2
20 x 18 = 360
14ft * 16 ft = 224 sq ft.
To determine how many 16 inch x 16 inch pavers are needed for a 20 ft x 20 ft patio, first calculate the area of the patio in square feet: 20 ft x 20 ft = 400 sq ft. Each 16 inch x 16 inch paver covers an area of 1.78 sq ft (16 in = 1.33 ft, so 1.33 ft x 1.33 ft = 1.78 sq ft). Dividing the patio area by the area of one paver gives: 400 sq ft ÷ 1.78 sq ft ≈ 224.7. Therefore, you would need approximately 225 pavers to cover the patio.
