Answer 1

$28.45

Explanation:

We need to find the area of the patio. The patio is rectangular in shape:

$\begin{gathered} Area\text{ of patio = area of rectangle} \\ Area\text{ of patio = length }\times width \\ \text{lenght = 14 ft, width = 10 ft} \\ \text{Area of patio = 14 }\times\text{ 10 } \\ \text{Area of patio = 140 ft}^2 \end{gathered}$

We are told 59 square feet of paint cost $11.99

We need to find the cost of paint required to paint the patio

let the cost of 140 square feet of paint for the patio = y

59 ft² = $11.99

140 ft² = y

cross multiply:

y(59 ft²) = 140 ft² ($11.99)

ft²cancels out on both sides:

59y = 140 ($11.99)

59y = $1678.6

y = $1678.6/59

y = $28.45

Hence, the estimated cost for painting the concrete is $28.45
