The perimeter of a rectangular window is 38 feet. the width of the window is 3 feet more than the height. what are the dimensions of the window?

N= height of window
n+3 = width of window

2 (n+n+3) =38  (2 times the sum of the two different sides is the same as the perimeter)

2(2n+3) = 38  
4n+6 = 38    (I combined like terms)
4n = 32 = (I subtracted 6 from both sides of the equation)
n=8  (I divided both sides by 4)
n=8 and n+3 = 11

Check  If the two sides are 8 and 11 then 1/2 way around the rectangle is 8+11=19 and all the way around is twice that or 38.

1/5 i hope this
