Question

partially correct
your answer is incorrect.
the figure below shows a rectangular window.
(a) use the calculator to find the area and perimeter of the window.
make sure to include the correct units.
area: ( 2356 \text{ in}^2 )
perimeter: ( 200 \text{ in} )
(b) the windows glass will be replaced.
which measure would be used in finding the amount of glass needed?
perimeter area
(c) a silver wire will be placed around the window.
which measure would be used in finding the amount of wire needed?
perimeter area

Explanation:

Step1: Calculate the area of the rectangle

The formula for the area of a rectangle is \(A = l\times w\), where \(l = 62\) in and \(w = 38\) in.
\(A=62\times38 = 2356\) \(in^{2}\)

Step2: Calculate the perimeter of the rectangle

The formula for the perimeter of a rectangle is \(P=2(l + w)\)
Substitute \(l = 62\) in and \(w = 38\) in.
\(P = 2(62+38)=2\times100 = 200\) in

Step3: Determine the measure for glass

Glass covers the surface of the window. Area measures the surface - enclosed by a shape. So, for the amount of glass (which covers the surface of the window), we use the area.

Step4: Determine the measure for wire

Wire is placed around the window. Perimeter measures the length around a shape. So, for the amount of wire (which goes around the window), we use the perimeter.

Answer:

(a) Area: \(2356\) \(in^{2}\), Perimeter: \(200\) in
(b) Area
(c) Perimeter
