(a) 10,4 m²
(b) 25,6 m²
(c) 12,8 m²
(d) 15,2 m²

The image of the room is in the attachment.

(c) 12.8 m²

Step-by-step explanation:

The area of a trapeze is calculated as:

A =

where:

B is bigger side

b is smaller side

h is height of trapeze

From the image, we have:

B = 3.8m

b = 2.6m

h = 4m

A =

A = (3.8+2.6).2

A = 12.8

The area of the trapeze is A = 12.8 m².

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
