Question

(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: Recall area formula for rectangle

The area formula for a rectangle is $A = l\times w$, where $l = 63$ in and $w = 38$ in. So $A=63\times38 = 2394$ in².

Step2: Recall perimeter formula for rectangle

The perimeter formula for a rectangle is $P=2(l + w)$. Substitute $l = 63$ in and $w = 38$ in. Then $P = 2(63+38)=2\times101 = 202$ in.

Step3: Determine glass - related measure

The amount of glass needed is related to the surface covered, so we use area.

Step4: Determine wire - related measure

The amount of wire needed to go around the window is related to the distance around the window, so we use perimeter.

Answer:

(a) Area: 2394 in²
Perimeter: 202 in
(b) Area
(c) Perimeter
