Answer 1

Step-by-step explanation:

6. Area of lawn= 8+2=10, 10+2=12 12×10=120 surrounded

10×8=80

120-80=40

Then total uncovered= 40 sq mAns

7. 30×24=720

30+3+3=36

24+3+3=30

36×30= 1080

1080-720=360 sq cmAns

8. 40×24= 960

24-3+3=18

40-3+3=34

34×18=612

960-612= 348 sq cmAns

9. 40×15m=600m

600÷6 heqtare

100 garden Ans

10. 22×15= 330

30 m into cm=3000

22 m into cm= 2200

3000×2200= 6600000

6600000÷330

20000 bricks Ans
