A concrete patio is
[tex]5 \frac{2}{3} [/tex]
feet wide. It has an area of
[tex]36 \frac{2}{3} [/tex]
square feet. is the concrete slab long enough to fit a 7-foot picnic table without placing the table along the diagonal of the patio? Explain. ​

Respuesta :

The length of concrete patio is 6.5 feet which is less than given 7 foot picnic table. So the concrete slab is not enough to fit a 7 foot picnic table

Solution:

Given that concrete patio is [tex]5\frac{2}{3}[/tex] feet wide

Area of concrete patio = [tex]36\frac{2}{3}[/tex] square feet

Therefore,

[tex]\texttt{Width of concrete patio = }5\frac{2}{3}=\frac{5\times 3+2}{3}=\frac{17}{3}feet\\\\\text{Area of concrete patio = }36\frac{2}{3}=\frac{36\times 3+2}{3}=\frac{110}{3}feet^2[/tex]

Let us find the length of concrete patio

Concrete patio is usually of shape rectangle

Area of concrete patio = length x width

[tex]\frac{110}{3} = length \times \frac{17}{3}\\\\length = \frac{110}{3} \times \frac{3}{17}\\\\length = \frac{110}{17} = 6.4705 \approx 6.5[/tex]

Therefore length of concrete patio is 6.5 feet

So it cannot fit the 7 foot picnic table. Since the length of concrete patio is 6.5 feet which is less than given 7 foot picnic table
