Question

(a) use the calculator to find the perimeter and area of the lawn. make sure to include the correct units. perimeter: area: (b) the lawn will be mowed. which measure would be used in finding how long it will take? perimeter area (c) the lawn will be surrounded by a rope. which measure would be used in finding how much rope to buy? 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, $l = 22$ ft and $w=19$ ft. So, $P = 2(22 + 19)$.

Step2: Calculate the perimeter

$P=2\times(22 + 19)=2\times41 = 82$ ft.

Step3: Recall area formula for rectangle

The formula for the area $A$ of a rectangle is $A=l\times w$. So, $A = 22\times19$.

Step4: Calculate the area

$A=22\times19 = 418$ ft².

Step5: Analyze mowing - related measure

The time it takes to mow a lawn depends on the amount of surface to be covered, so we use the area.

Step6: Analyze rope - related measure

The length of rope needed to surround the lawn is equal to the perimeter of the lawn.

Answer:

Perimeter: 82 ft
Area: 418 ft²
(b) Area
(c) Perimeter
