the width of a rectangle is the length - 6 units. The area of the rectangle is 27 units. what is the length, in units, of the rectangle?

The legth of the rectangle is 4.5 units

Step-by-step explanation:

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
