Question

What will be the area, in square feet, of the poster?

Answer 1

b

Explanation:

first you need to see how many times `1 1/4` goes into both `12 1/2` and `17 1/4`. this will tell you how many feet each unit represents.

`12 1/2 / 1 1/4 = 10`

`17 1/4 / 1 1/4 = 13 8/10`

it is easier to it in decimal form

`12.5 / 1.25 = 10`

`17.25 / 1.25 = 13.8`

area equals length times width

`10 * 13.8 = 138`
