Question

david wants to replace a glass window in his restaurant. the window is in the shape of a square. its side lengths are 11 feet. suppose glass costs $5 for each square foot. how much will the glass cost to replace the window?

Explanation:

Step1: Calculate window area

The area formula for a square is $A = s^2$, where $s$ is the side - length. Given $s = 11$ feet, so $A=11^2=121$ square feet.

Step2: Calculate total cost

The cost per square foot is $\$5$. Multiply the area by the cost per square foot. So the total cost $C = 121\times5 = 605$.

Answer:

$605$
