Analysis: This question examines the application of mixed four operations. According to the topic, calculate the length and width of the rectangle first, and then calculate the area.

The problem solving process is as follows:

Solution: This stage can be divided into two squares, indicating that the length is twice the width.

Width =96÷2÷(2+ 1)

=96÷2÷3

= 16 (m)

Length = 16×2=32 (m? )

Area: 32× 16=5 12 (square meter)?

A: The rectangular stage covers an area of 5 12 square meters.

Extended data:

operation sequence

When calculating at the same level, calculate from left to right in turn;

Two-stage operation, first multiply and then divide, then add and subtract.

When there are brackets, count the inside of brackets first, and then count the outside of brackets;

When there are multiple brackets, count the brackets first, then the brackets inside, then the braces inside, and finally the brackets outside.

If there is a power, calculate the power first.

When performing mixed operations, the numbers in parentheses are calculated first, and the parentheses are from small to large. If there is a power, calculate the power first, and then from high to low.
