A piece of string is 28 cm long. It is used to from a square. (a) what is the length of each side of square? (b) what is the area of the square.?​

7 cm and 49 cm²

Step-by-step explanation:

(a)

A square has 4 equal sides , then

28 cm ÷ 4 = 7 cm

The length of each side of the square is 7 cm

(b)

The area (A) of a square is

A = s² ( s is the side length ) , then

A = 7² = 49 cm²

Step-by-step explanation:

Perimeter of square will be equal to the length of the  string

Perimeter of square = 28 cm

4*side = 28

Divide both sides by 4

Side = 28/4

Side = 7 cm

b) Area of square = side * side

                             = 7 * 7

                             =49 cm²

it is definatly the 3rd one. very much looks like it, for a good chance, the third one would be best for you.

8(4)^8=72^feet to say that the total can conclude to 8(4) which as you know would mean 8 x 4. that equals 32w. 32^ could make a 72 answer as well. but your coefficent will remain w so your answer is 72w.
