Question 193102: A rectangular picture frame is 4 times as wide as its length with a perimeter of 80 inches. Find the dimensions. Answer by orca(409) (Show Source):
You can put this solution on YOUR website! Let x be the length.
Then its width 4x
So the perimeter in terms of x is 2(x + 4x)
Setting it equal to 80, we have
2(x + 4x) = 80
Solving for x, we have
2*5x = 80
10x = 80
x = 8
Therefore the length is 8
the width is 4x = 4*8 = 32
