An architect is creating a scale drawing of a school computer lab. The length of the lab is 32 feet and the width of the lab is 48 feet. If each 16 feet of the lab equals 2 centimeters on a scale drawing, which of the following drawings is the scale drawing of the computer lab?

The answer is B

Step-by-step explanation:

Length:

32ft. / 16ft. = 2

2 x 2cm. = 4 cm.

Width:

48ft. / 16ft. = 3

3 x 2cm. = 6cm

b

Step-by-step explanation:

The largest advertisement she can afford has dimensions of 5 in x 10/3 in

Step-by-step explanation:

Assume the dimensions of the advertisement are L and W.

The area of the advertisement is:

A = L.W

The ratio length/width is 3:2, thus the proportion is:

Thus:

The area is:

Since the square inch of advertisement space sells for $3, the cost for Anna to purchase it is:

Simplifying:

This cost can be a maximum of $50, thus:

Multiplying by 2:

Solving for W:

And

L = 5

Thus the largest advertisement she can afford has dimensions of 5 in x 10/3 in
