To determine how many 16x16 pavers are needed for a 5x5 patio, first calculate the area of the patio and the area of one paver. The patio area is 5 feet x 5 feet = 25 square feet. Each 16x16 paver covers 2.67 square feet (16 inches = 1.33 feet, so 1.33 x 1.33 ≈ 1.78 square feet). Dividing the patio area by the paver area, you need approximately 10 pavers (25 ÷ 1.78 ≈ 14). Therefore, you would need about 15 pavers to cover the patio area completely.

Area of 1 paver = 16*16 = 256 square units. Area of patio = 20*20 = 400 square units. Number of pavers required = Area of patio/Area of paver = 400/256 = 1.5625 So 2 pavers will suffice.
