Brick = 3.5 in by 7.5 in and costs $0.59
Paver = 8.4 in by 8.4 in and costs $1.88
The small patio's area = 3430 square inches
The Area of 1 Brick = 26.25 square inches
The Area of 1 Paver = 70.56 square inches
The # of Bricks to complete the Patio will be:
Patio's Area / the Area of 1 Brick = # of Bricks to complete the patio
3430 square inches / 26.25 square inches = 130.67 = 131
Then, multiply the # of Bricks to complete the patio by the amount that 1 brick costs:
131 * $0.59 = $77.29
It will take $77.29 to complete the Patio with bricks.
The # of Pavers to complete the Patio:
Patio's Area / the Area of 1 Paver = # of Pavers to complete the Patio
3430 square inches / 70.56 square inches = 48.6 = 49
Then, multiply the # of Pavers to complete the patio by the amount that 1 Paver costs:
49 * $1.88 = $92.12
Cost of Bricks to complete Patio = $77.29
Cost of Pavers to complete Patio = $92.12
To conclude, Bricks would cost less by $14.83.
A)He can cut 5 strips of of 7/10m.
7/10=0.7m
0.7*5=3.5m
3.5m of wire wil be used in cutting possible 7/10m pieces.
b)Leftover will be 0.6m.
4.1-3.5=0.6m
Divide the numerator and the denominator of the given rate by the denominator of the given rate. so in this case, divide the numerator and denominator of 70/5 by 5 to get 14/1 or 14 students per class
