Can somebody please help me out? I really need to get this right.

(I dunno if you know how to find the area of the trapezoid, so I included this wordy directions)

Add the top/first base plus the second/bottom base together.

Multiply that with the height.

After, divide that by two.

3 cm + 6 cm = 9 cm

9 cm x 4 cm = 36 cm

36 cm /2 = 18 cm

Area of trapezoid: 18 cm^2

So using the given information about (original) larger area of trapezoid being 72 cm^2,,,

,,,we would get 1/4 if we divide 18/72.

(scale factor)^2 = (1/4)

= 1/2

so what is the question

step-by-step explanation:

if you are saying purchasing 3 social media ads and one newspaper ad counts as one purchase then there are:

6 purchases

if you are asking how many of each then:

18 social media ads

6 newspaper ads
