Question

(a) use the calculator to find the perimeter and area of the window. make sure to include the correct units. perimeter: area: (b) a silver wire will be placed around the window. which measure would be used in finding the amount of wire needed? perimeter area (c) the windows glass will be replaced. which measure would be used in finding the amount of glass 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, $l=69$ in and $w = 37$ in. So, $P=2(69 + 37)$.

Step2: Calculate the perimeter

$P=2\times106=212$ in.

Step3: Recall area formula for rectangle

The formula for the area $A$ of a rectangle is $A=l\times w$. So, $A = 69\times37$.

Step4: Calculate the area

$A=2553$ in$^{2}$.

Step5: Determine wire - related measure

The amount of wire needed to go around the window is given by the perimeter as it measures the length around the shape.

Step6: Determine glass - related measure

The amount of glass needed to cover the window is given by the area as it measures the surface space.

Answer:

(a) Perimeter: 212 in
Area: 2553 in$^{2}$
(b) Perimeter
(c) Area
