Step-by-step explanation:
20^2-18^2=76
square root of 76 is 8.7 to the nearest tenth
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.
