Question

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

Answer 1

The length is 9 units.

Explanation:

x will be our length so we get:

x*(x-6)=27

You can just try the factors of 27 as x.

Let's guess x is 9

9*(9-6)=27

9*3=27

Which is true, so the length must be 9 and the width must be 6.
