Estimate width of the hall is 90 feet.
Step-by-step explanation:
Given: The area of rectangular banquet hall is 7400 square feet and the length of one side of the hall is 82 feet.
To find the width of the hall.
Area of rectangular is multiply the length by width.
i,e
......[1] ; where A is the area of rectangle, l is the length and w is the width of the rectangle respectively.
Substitute the value of A = 7400 square feet and length(l) = 82 feet in [1] to solve for w;

Divide both sides by 82 we have;
= 90.24 feet ≈ 90 feet.
therefore, the width of the hall is 90 feet.
