A = s^2 and P = 4s. 
So if A = 25, then s^2 = 25 so s = 5. Then 4*s = 4*5 = 20 
The perimeter of a square with an area of 25cm^2 is 20cm. 
Increase the perimeter by 4 to get 24cm. Then 4s = 24 implies s = 6. Then s^2 = A = 6^2 = 36. 
Now the area is 36 cm^2

Marisa bought four bottles of water.Each bottle of water was 95 cents. Write an equation with the same product as the total cost
meriva

Answer:

5\times 0.76= 3.8

Step-by-step explanation:

Given: Marisa bought four bottles

          Price of each bottle is $0.95.

Solving with the factors as given to find the total cost paid by Marisa.

Total cost= 4\ bottles\times \$ 0.95= \$ 3.8

∴ Total cost paid by Marisa is $3.8.

As given to write an equation with the same product as the total cost but different factors.

∴ Lets assume the number of bottles bought by Marisa be "5" and cost of each bottle be "x"

We already find the total cost she paid is $3.8.

Now, writing an equation with different factors, as total cost remain same.

5\times x= 3.8

Dividing both side by 5

we get x= $ 0.76

∴ The required equation is 5\times 0.76= 3.8
