A rectangular sandbox has a width that's 1⁄4 of its length. The total area of the sandbox is 36 square feet. Find the dimensions of the sandbox

Respuesta :

Answer:

Dimensions of box

Length is 12 feet

Width is 3 feet

Step-by-step explanation:

Let's assume length of sandbox is L

width of box is W

we are given

A rectangular sandbox has a width that's 1⁄4 of its length

so, we can write as

[tex]W=\frac{1}{4}L[/tex]

we know that

area = length*width

so, we get

[tex]A=L\times W[/tex]

now, we can plug back W

[tex]A=L\times \frac{1}{4}L[/tex]

we can set Area=36

[tex]36=L\times \frac{1}{4}L[/tex]

now, we can solve for L

[tex]L^2=144[/tex]

[tex]L=12[/tex]

now, we can find W

[tex]W=\frac{1}{4}\times 12[/tex]

[tex]W=3[/tex]

So, dimensions of box

Length is 12 feet

Width is 3 feet
