Question

Eric created a rectangular patio 1 ft.² paving stones which are sold in batches by a dozen the patio measures 7‘ x 8‘ how many batches of Pavingstone did Eric need

Answer 1

The number of batches of paving stones Eric needs is 5 batches

Explanation:

Here we have the size of of one paving stone = 1 ft²

The dimensions, size, of one patio = 7 ft × 8 ft = 56 ft²

Therefore, the number of paving stones Eric needs per patio is given by the relation;

`Number\, of\ paving\ stones \ required =(size\, of \, one\, patio)/(size \, of \, one\, paving\, stone) = (56 \, ft^2)/(1 ft^2/(paving \, stone)) = 56 \, paving \, stones`

Since the paving stones are sold in batches of one dozen, we have ;

4 batches = 48 paving stones and 5 batches = 60 paving stones

Therefore, the number of batches of paving stones Eric needs = 5 batches.
