Answer 1

The billboard should be 30 feet tall

Explanation:

Height of the picture = 5 inches

Width of the picture = 8 inches

But the billboard has a width of 48 feet = 12 x 48

= 576 inches

To know how tall the billboard is, we have to determine the scale factor required.

scale =
`(width of billboard)/(width of picture)`

scale =
`(576)/(8)`

= 72

scale = 72

The height of the billboard = scale x 5 inches

= 72 x 5 inches

= 360 inches

Also,

The height of the billboard =
`(360)/(12)`

= 30 feet

Therefore, the billboard would be 30 feet tall.
