Question

The producers of a concert are going to use

television screens to show larger-than-life images
of the band using a scale of 2 inches = 3 feet.
The lead singer of the band is 6 feet 2 inches tall,
now tall will the singer be on the screen?
144 feet
111 fost
63 feet
9 feel

Answer 1

111 feet

Explanation:

The scale used to blow up the the lead singer (and the band) is

2 in : 3 feet

==> 1 in : 3/2 feet

Let X be the height of the band leader in inches and the blown-up image be Y

X = 6' 2" = 6 x 12 + 2 = 72 + 2 = 74"

Then Y = (3/2) x H

Y = (3/2) x 74" = 111 feet
