The area of a rectangle banquet hall is 7400 square feet. the length of one side of the hall is 82 feet. explain how you can use compatable numbers to estimate the width of the hall

We are given that the hall has a rectangular shape.
Area of rectangle can be calculated using the following rule:
Area of rectangle = length * width

We are also given that:
Area = 7400 square feet
length = 82 feet

Substitute with the givens in the above equation to get the width as follows:
Area of rectangle = length * width
7400 = 82 * width
width = 7400 / 82
width = 90.24390244 feet
