The legth of the rectangle is 4.5 units
To solve this we first have to know the formula to calculate the area of a rectangle
a = area 27 square units
l = length
w = width = 6 units
a = l * w
because we want to calculate the length, we will have to clear the l
a = l * w
l = a / w
now we replace with the known values
l = 27 u² / 6u
l = 4.5 u
