1 дм = 10 см

1 дм² = 1 дм * 1 дм = 10 см * 10 см = 100 см²

55 000 дм² = 55 000 * 100 = 5 500 000 см²

55 000 дм² - 500 см² = 5 500 000 см² - 500 см² = 5 499 500 см² =

= 54 995 дм²

800 м² : 4 м² = 200

1 ар = 100 м²

500 ар = 500 * 100 = 50 000 м²

32 000 м² + 500 ар = 32 000 м² + 50 000 м² = 82 000 м² = 820 ар

20 см² + 2000 см² = 2020 см²

1 ар = 100 м²

800 м² + 1 ар = 800 м² + 100 м² = 900 м² = 9 ар

1 га = 100 ар

50 га = 50 * 100 = 5000 ар

50 га - 50 ар = 5000 ар - 50 ар = 4950 ар = 49,5 га = 49 га 50 ар

Thanksgiving Dinner
Last Thanksgiving my parents had a large family dinner at their house. Getting ready for Thanksgiving dinner
takes a lot of work.
The day started well and by late afternoon we had completed most of the work. Everyone had helped to make
the meal a success. We had put the turkey in the oven earlier that day so the house was starting to smell like roast
turkey. The grandchildren had finished setting the table for Thanksgiving dinner. My aunt had made two pies for
dessert, a pumpkin pie and an apple pie. My brother and I had peeled the carrots and the potatoes. We had just turned
on the stove to start cooking the vegetables when the power went out! The oven stopped working! We couldn’t cook
the vegetables! The turkey wouldn’t finish cooking! We waited. We talked. We went for a walk.
We had waited two hours by the time the power came back on. We had almost given up hope. Dinner was late
that night but it was a Thanksgiving dinner that we won’t forget.
