Verb (abbreviation of verb) Application question (8 points for each small question *** 32 points) 1 In this question, the total amount of grain stored in two granaries, A and B, remains unchanged. If the two warehouses store the same grain, it is necessary to divide 1038 tons into two granaries on average, so that 1038÷2=5 19 (tons). If the two warehouses each have 5 19 tons, the stored grain is the same, but it is the same after warehouse A gives 9 tons to warehouse B, indicating that warehouse A is 9 tons more than warehouse B's 5 19 tons, while warehouse B is 5 19 tons.
1038÷2=5 19 (ton)
5 19+9=528 (ton)
5 19-9=5 10 (ton)
A: It turns out that warehouse A has 528 tons of grain and warehouse B has 565,438+00 tons.

Analysis and solution: If you want to find the area of a rectangle, you must know its length and width. The perimeter is the sum of two lengths and two widths. If the width is 1 times and the length is twice as wide, then the total length is equivalent to the width of 1+2=3 (times). Then you can find out the width and the corresponding length. Knowing the length and width, you can work out the area of a rectangle.
54÷2=27 cm
1+2=3
27÷3=9 cm
9×2= 18 (cm)
9× 18= 162 (square centimeter)
Answer: The area of rectangular wooden board is 162 square centimeters.
4. Analysis and solution: If you want to find the area of a rectangle, you must know its length and width. The perimeter is the sum of two lengths and two widths. If the width is 1 times and the length is twice the width, the total length is equivalent to 1+2=3 (times) of the width. So you can find the width and length accordingly. If you know the length and width, you can find the rectangle.
54÷2=27 cm

27÷3=9 cm
9×2= 18 (cm)
9× 18= 162 (square centimeter)
Answer: The area of rectangular wooden board is 162 square centimeters.
