Answer:
Option A is correct.
The length of each side of the window is, 20 inches
Step-by-step explanation:
As per the given statement: The perimeter of a church window is 80 inches.
Since, the window is in the shape of a square.
Perimeter of square :
For a square of side length a, the perimeter(P) is simply four times the side length i.,e P = 4a
To solve for a;
P = 4a
Substitute the value of P = 80 inches, we have;
80 = 4a
Divide both sides by 4 we get;
\(\frac{80}{4} =\frac{4a}{4}\)
Simplify:
a = 20 inches
Therefore, the length of each side of the window is, 20 inches
