Question

(34 дм2 + 56 дм2) : 3 = (62 м2- 53м2) ∙ 4 =

Answer 1

1) =(90дм²):3=30дм²
2) =(9м²)*4=36м²

Answer 2

Let's solve the expression step by step:

1. (34 дм^2 + 56 дм^2) : 3

First, add the areas inside the parentheses:

34 дм^2 + 56 дм^2 = 90 дм^2

Now, divide the result by 3:

90 дм^2 : 3 = 30 дм^2

So, (34 дм^2 + 56 дм^2) : 3 = 30 дм^2

2. (62 м^2 - 53 м^2) ∙ 4

First, subtract the areas inside the parentheses:

62 м^2 - 53 м^2 = 9 м^2

Now, multiply the result by 4:

9 м^2 ∙ 4 = 36 м^2

So, (62 м^2 - 53 м^2) ∙ 4 = 36 м^2

In conclusion, the final expression is:

(34 дм^2 + 56 дм^2) : 3 = 30 дм^2

(62 м^2 - 53 м^2) ∙ 4 = 36 м^2
