Question

The width of a rectangle is the length minus 1 units. The area of the rectangle is 72 units. What is the width, in units, of the rectangle?

Answer 1

The width of the rectangle should be 8 units.

Calculation of the width:

Since The width of a rectangle is 1 units less than the length. The area of the rectangle is 72 units.

Here we know that

Area = (length) (width)

Here we assume length be x

So, width be = x - 1

So,

(x) (x - 1) = 72

(x + 8) (x - 9)

So, the width should be

= 9 - 1

= 8

hence,
