Answer:
Length of the room is 180 ft
Step-by-step explanation:
We have a rectangular room with dimensions:
width = 70 ft and length "x" (unknown)
Perimeter of a rectangle is 2*w + 2*x and according to problem statement 500 ft of lights will fit exactly in room perimeter then:
2*70 + 2*x = 500
140 + 2*x = 500
2*x = 500 - 140
2*x = 360
x = 360/2
x = 180 ft
So we want to find how much more space the logo took up.
So just subtract the location info from the logo space.
2/7 - 1/10
To subtract, you just want to find a common denominator. In this case it would be 70.
2/7 * 10/10 - 1/10 * 7/7
20/70 - 7/70
Then just subtract.
13/70
So that's the fraction. For the percent, just divide.
13/70 = 0.186 ish
Or, 18.6% ish
