6: A bricklayer charges $8 per square foot to lay a patio. How much would it cost for the bricklayer to lay a 12-foot-×-16-foot patio?
A. $960
B. $192
C. $224
D. $1536
First you need to know how many square feet by figuring the area
Area = lw = 12*16 = ?
take the answer from above (?) and multiply by $8/sq ft. for your answer
To find the cost of laying a 12-foot × 16-foot patio, we need to calculate the area of the patio and then multiply it by the cost per square foot.
The area of the patio is calculated by multiplying the length (12 feet) by the width(16 feet):
Area = Length × Width = 12 ft × 16 ft = 192 square feet.
Now, to find the cost for the bricklayer to lay the patio, we multiply the area by the cost per square foot:
Cost = Area × Cost per square foot = 192 sq ft × $8/sq ft = $1536.
Therefore, the correct answer is D. $1536
