PLease i need help i dont understand and i need an explantaion

c) 56 m²

Step-by-step explanation:

Area of the figure =  area of triangle + area of rectangle

Rectangle:

length = 8 m

Width = 5 m

Area = length * width

       = 8 *5

       = 40 m²

Triangle:

base (b)= 4 m

height (h) =  8 m

= 2* 8

=  16 m²

Area of the figure = 40 + 16

                                = 56 m²

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
