Bài 3:
Để tính chu vi của tam giác, ta cần cộng tổng độ dài của 3 cạnh. Trong trường hợp này, cạnh thứ nhất có độ dài 7,8 dm, cạnh thứ hai dài hơn cạnh thứ nhất 3,2 dm (tức là 7,8 + 3,2 = 11 dm), và cạnh thứ ba có độ dài 10,5 m (tức là 1050 dm).

Chu vi của tam giác là tổng độ dài các cạnh:

7,8 + 11 + 1050 = 1068,8 dm

Vậy chu vi của tam giác là 1068,8 dm.

Bài 4:
Để tính tổng các số, ta cộng các số lại với nhau:

37,05 + 18,01 + 42,95 + 21,09 + 6,25 + 0,7 + 3,75 + 0,3 = 130,1

Vậy kết quả là 130,1

Đổi 10,5m=105dm

Chu vi của tam giác đó là:

7.8+(7.8+3.2)+105=123.8(dm)

Bài 4:

a=37,05+18,01+42,95+21,09+6,25+0,7+3,75+0,3

 =(37,05+42,95)+(18,01+21,09)+(6,25+3,75)+(0,7+0,3)

 =80+39,1+10+1=130,1.

Review of the musical "Cats":

I recently attended the musical "Cats" with my friend last night. Overall, it was a fun and beautiful experience with a happy ending. The performances were energetic and entertaining, keeping the audience engaged throughout the show.

One aspect that stood out was the vibrant and colorful set design, which added to the visual appeal of the production. The costumes and makeup of the actors were also impressive, bringing the feline characters to life in a captivating way.

However, one minor drawback was the volume of the music and sound effects. At times, it felt a bit too loud, making it slightly difficult to fully appreciate the dialogue and lyrics. Nonetheless, this did not significantly detract from the overall enjoyment of the performance.

In conclusion, "Cats" was a delightful musical with its lively performances, stunning visuals, and a satisfying conclusion. Despite the occasional issue with the volume, I would still recommend it for anyone looking for an entertaining and visually appealing theater experience.
