Question

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

The formula for the perimeter $P$ of a rectangle is $P = 2(l + w)$, where $l$ is the length and $w$ is the width. Here, $l=63$ in and $w = 13$ in. So $P=2(63 + 13)$.

Step2: Calculate the perimeter

$P=2\times76=152$ in.

Step3: Recall area formula for rectangle

The formula for the area $A$ of a rectangle is $A=l\times w$. So $A = 63\times13$.

Step4: Calculate the area

$A = 819$ in².

Step5: Determine glass - related measure

The amount of glass needed is related to the surface covered, which is the area.

Step6: Determine wire - related measure

The amount of wire needed to go around the window is related to the perimeter.

Answer:

(a) Perimeter: 152 in
Area: 819 in²
(b) Area
(c) Perimeter
