3 4-(Book 5 6-2 6).

4. There is a common area here, 1 4 of the grassland = 1 7 of the bamboo forest, and the rest is the area for comparison, that is.

6 7 times the area of the bamboo forest - 3 4 times the area of the grassland = 6 7 times the area of the bamboo forest - 3 7 times the area of the bamboo forest = 450

3 7 multiplied by the bamboo forest area = 450, do not need to calculate the bamboo forest area, directly calculate 1 7 bamboo forest area = 450 3 = 150 square meters.

5. Here you can first calculate the side length of the small square = 4 4 = 1 decimeter, then the area of the small square is 1 1 = 1 square decimeter.

The area of the small square of the shadow = 1 1 (1+3) = 1 4 square decimeters, and the area of the large square = 1 4 8 = 2 square decimeters.

9 = 1062 (pcs).

Article 4: 118 9 = 1062 (pcs).

A: There are 1,062 tables in total.

Article 5: 860-365-406 = 89 (m) Answer: There are 89 meters left.

118x9=1062 (pcs).

A: There are a total of 1062 seats.

365 + 406 = 771 (m).

860-771 = 89 (m).

A: There are still 89 meters left to finish.

Hope it helps!

4. Solution: 118*9=1062 (pcs).

A: There are a total of 1062 seats.

5. Solution: 860-365-406=89 (m) Answer: There are still 89 meters left to pour.

Article 4: 118 9 = 1062 (pcs).

A: There are 1,062 tables in total.

Article 5: 860-365-406 = 89 (m) Answer: There are 89 meters left.

4118 9 = 1062 (pcs).

A: There are 1,062 tables in total.

5860-(365+406)=89 (m).

A: There are still 89 meters left.

Circumference = (196-16*4) 2 = 132 2 = 66 cm.

Assuming that the length and width are x,y respectively, then: 4x+4y+16*4=196, so x+y=33

The perimeter of the rectangle is known, and the area is largest only when length=width=33 2=, but since it can only be taken as an integer.

When the length = 16 and width = 17, the area is the largest, and the area = 16 * 17 = 272 cm.
