Answer:
Dimensions of box
Length is 12 feet
Width is 3 feet
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
we know that
area = length*width
so, we get
now, we can plug back W
we can set Area=36
now, we can solve for L
now, we can find W
So, dimensions of box
Length is 12 feet
Width is 3 feet
