The first part: rectangle, 2*6= 12.

The second and third parts: trapezoid, respectively: (4.6+ 10)*3/2=

(2+6.6)*3/2

Part IV: Triangle, 3.2*3/2

Add up the total area.

(2) Small trees can be regarded as rectangles, with a length of 15 and a width of 10, and six trees can be cut down. Or the area of the triangle: (1+1+0.6+0.6) nbsp; ×3÷2=4.8 (square centimeter) Small trapezoidal area: (1+1+2.3+1+)× 3 ÷ 2 =12.9. (square centimeter) Rectangular area: 2× 6 =12nbsp; (square centimeter) Small tree area: 4.8+12.9+18.9+12 = 48.6nbsp; Its area is 48.6 square centimeters.
