Question

The area of a rectangle is 81m'n' square units. If the length of the rectangle is 9mn', how many

units wide is the rectangle?

Answer 1

9

Explanation:

9x9=81

Answer 2

Explanation:

So the rectangle is 9 units wide.

becuase given that the area of the rectangle is 81m'n' square units and the length of the rectangle is 9mn', we can set up the equation as:

81 = 9 x width

To solve for width, we can divide both sides of the equation by 9:

width = 81/9

width = 9
