ans:
let height of the window = h
width of the window = w
hence according to the question
h = 0.80*w -------I
perimeter = 2(h+w) = 162"
putting h from eq. I
2(.8*w + w)=162
or 2*1.8*w = 162
or w = 162/3.6 = 1620/36 = 45"
hence h = .8*45 = 36"

Let width (W) =x
The height (H)= 80%/100%*x=.80x
Perimeter (P)=162 in.
The formula for the perimeter is
162=2(x)+2(.80x)
162=2x+1.6x
162=3.6x
45=x
The width: x=45 in.
The length: .80x=.80(45)=36 in
:
Check:
162=2(45)+2(36)
162=90+72
162=162 We're right!!!
Happy Calculating!!!
