A window is being replaced with tinted glass. The plan below shows the design of the window. Each unit length represents 1 foot. The glass costs $14 per square foot. How much will it cost to replace the glass? Use 3.14 for it.

In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data
lenght unit = 1 ft
glass price = $14 peer square foot
total cost = ?
Step 02:
Circumference area
Ac = π * r ²
r = 2 ft
Ac = 3.14 * (2ft)² = 12.56 ft²
Parallelogram area
Ap = b * h
b = 5 ft
h = 4 ft
Ap = 5ft * 4ft = 20 ft²
Total Area :
At = Ac + Ap = 12.56 ft² + 20 ft² = 32.56 ft²
Step 03:
Total cost:
[tex]tc=32.56ft^2\cdot\frac{14\text{ \$}}{1ft^2}\text{ = }455.84\text{ \$ }[/tex]The answer is:
The total cost will be $455.84.
