(a) use the calculator to find the area and perimeter of the window.
make sure to include the correct units.
area:
perimeter:
(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

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

Step2: Calculate the perimeter

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

Answer:

Area: \(2356\) \(in^{2}\)
Perimeter: \(200\) in
