To cover a garden path a landscape designer plans to cover a walkway with parallelogram
pavers. The designer calculates that the walkway is 10 feet wide and 20 feet long. Each paver is 1.5 feet by 1 foot.
To calculate how many pavers are needed, the designer multiplies the width of the walkway by the length: 10 feet x 20 feet = 200 square feet.
Next, the designer calculates the area of one paver: 1.5 feet x 1 foot = 1.5 square feet.
Dividing the total area of the walkway by the area of one paver gives the number of pavers needed: 200 square feet ÷ 1.5 square feet = 133.33 pavers.
Since you can't have a fraction of a paver, the designer rounds up to the nearest whole number. Therefore, the landscape designer will need 134 pavers to cover the garden path.
