A storefront window has 154 square feet of glass. the window is 7 feet tall. what is the perimeter of the window?
goblinko [34]
The area of the of the storefront window made of glass in question is = 154 square feet
The length of the glass window that is given in the question is = 7 feet
Let us assume the Width of the glass window in question to be = x feet
Then
Area = Length * Width
154 = 7 * x
7x = 154
x = 154/7
  = 22 feet
So we come to know that the width of the glass window in question is 22 feet.
Now
Perimeter of the glass window = 2 ( Length + Width)
                                                   = 2 (7 + 22) meters
                                                   = 2 * 29 meters
                                                   = 58 meters.
So the perimeter of the glass window as can be seen from the above deduction is 58 meters.
