On a blueprint, an architect uses a scale of 3 cm : 8 ft. If a building is drawn to be 42 cm tall, what is the height of the actual building?

112 feet

Step-by-step explanation:

3 x 14 = 42

8 x 14 = 112

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
