Ответ:
75 square feet.
Step-by-step explanation:
So all you're going to do is simply cross multiply.
1/30 = 4/x (we put x because we don't know what number goes there)
SO 1 x X = x= 4x 30+ 120 so, x=120 in.
Now we do the same to the other one.
1/30 = 3/x
1 x x = x= 3x 30 = 90 so, x=90 in.
Wait, we are not done yet. It also says to find the area of the room in sq ft.
We need to convert these numbers into feet. So divide 12 by the numbers.
90/ 12 = 7.5 120/12 = 10 Now, we can multiply to get the square feet.
7.5 x 10 = 75 square feet.
