Answer
It would be less expensive to use bricks.
It would be less by ($91.3889 - 71.0933) = $14.2956
Explanations
Area of patio to be build = 70 × 49
= 3,430 in²
Area covered by 1 brick = 7.5 × 3.5
= 26.25 in²
Number of bricks needed to build the patio = 3430 ÷ 26.25
= 130 2/3 bricks
Cost of building the patio = 130 2/3 × $0 59
= $77.0933
Area of one paver = 8.4 × 8.4
= 70.56 in²
Number of pavers = 3430 ÷ 70.56
= 48 11/18 pavers
cost of bulding using paver = 48 11/18 × $1.88
= $91.3889
