A rectangle is drawn so that the width is I feet shorter than the length. The area of the rectangle
is 12 square feet. Find the length of the
rectangle,

Length = 4 feet

Step-by-step explanation:

Let the length of a rectangle be x.

Width is 1 feet shorter than the length, b = x-1

The area of the rectangle is 12 sq feet.

The area of a rectangle is given by :

A = length × width

So,

Neglecting the negative side, the length of the rectangle is equal to 4 feet.

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
