Question

A-?в 2 раза больше.b-4см. P-?см

Answer 1

4:2=2(а)
Р=(а+в)•2
Р=(4+2)•2=12см2

Answer 2

To solve for the perimeter (P) of the shape, we need more information about the shape itself. The information provided mentions that "A-?в 2 раза больше" (meaning "A is 2 times larger"), and "b-4см" (meaning "b is 4 cm"), but it doesn't specify the shape or the relationship between A and b.

Assuming that A refers to the length of one side of the shape and b refers to another side, and considering that A is twice as large as b, we can set up the relationship as:

A = 2b

With this information, we can't determine the actual lengths of A and b since one value is missing. As a result, we can't find the perimeter (P) without more information about the shape or the specific values of A or b. Please provide additional details or clarify the information given to get a more accurate answer.
