The perimeter of a square is 80 cm. What is the area?

A = 400 cm^2

Step-by-step explanation:

The perimeter of a square is given by

P = 4s where s is the side length

80 = 4s

Divide each side by 4

80/4 = 4s/4

20 =s

We want to find the area of the square

A = s^2

A = 20^2

A = 400 cm^2

4 bowls

Step-by-step explanation:

Conversion rate :

1 liquid pint = 16 fluid ounces

From the question, we are told that :

4 fluid ounces of bubble mix = 1 bowl

16 fluid ounces of bubble mix(1 liquid pint) = y bowl

Cross Multiply

4 fluid ounces × y bowl = 16 fluid ounces × 1bowl

y bowl = 16 fluid ounces × 1bowl/4 fluid ounces

= 4 bowls

Therefore, he can fill 4 bowls with 1 pint of bubble mix
