ch4aika [34]

Answer:

10.125 feet.

Step-by-step explanation:

you can use the rule of three to answer this question, the data we have is:

inches      feet

     1      →   4 1/2

  2 1/4    →   x

tha last table just indicates what the problem tells us, that one inch is equal to 4 1/2 feet and we want to know how much in feet the 2 1/4 inches are.

For this we multiply the cross quantities:

x=(2\frac{1}{4} )(4\frac{1}{2} )=2.25*4.5=10.125 ft

the actual length of the kitchen is 10.125 feet.
