In order to welcome the Spring Festival, the gardeners plan to place chrysanthemums and cyclamen in the open space of the square. ? Chrysanthemum \x09 each tree covers an area of 0.5 square meters \x09 each 6 yuan.

Cyclamen \x09 each tree covers an area of 0.8 square meters \x09 each 2 yuan.

Unit meter? (1) How many square meters does the chrysanthemum cover? (2) Is it enough to fill this triangle with chrysanthemums and buy flowers with 200 yuan? (3) What other questions can you ask? ? The right triangle is the chrysanthemum land, and the isosceles triangle is the cyclamen land.

1. Because the area of planting chrysanthemums is trapezoidal, the area formula of the trapezoid is: (upper bottom+lower bottom) × height ÷2, that is,

(2+5) × 6 ÷ 2 = 2 1 (square meter)

A: Chrysanthemum covers an area of 2 1 square meter.

2. The triangle he said is also a place for fairy tourists, so it is: 24× 0,5 = 48 (tree).

48× 6 = 288 (yuan)

8× 6 ÷ 2 = 24 (square meter)

288>200

A: Not enough.

3. You can ask: How many square meters does cyclamen cover?

8× 6 ÷ 2 = 24 (square meter)

A: Cyclamen covers an area of 24 square meters.
