The family size bottle of sunscreen holds 1212 fluid ounces (\text{fl oz})(fl oz) of sunscreen. the regular bottle holds 75\%75% less.

The regular bottle holds 303 fl oz of sunscreen.

Step-by-step explanation:

to find out what 75% of 1212 is, multiply 1212 by .75.

1212 x .75 = 909

Since the regular size bottle is 75% LESS than the family size, subtract 909 fl oz from 1212 fl oz.

1212 - 909 = 303.

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
