Question

(a) use the calculator to find the perimeter and area of the field. make sure to include the correct units. perimeter: area: (b) laura will walk around the field. which measure would be used in finding how long it will take? perimeter area (c) the field will be covered by artificial turf. which measure would be used in finding the amount of turf needed? perimeter area

Explanation:

Step1: Recall perimeter formula for rectangle

The perimeter formula of a rectangle is $P = 2(l + w)$, where $l$ is the length and $w$ is the width. Here, $l = 72$ yd and $w = 28$ yd. So $P=2(72 + 28)$.

Step2: Calculate the perimeter

$P=2\times100=200$ yd.

Step3: Recall area formula for rectangle

The area formula of a rectangle is $A=l\times w$. So $A = 72\times28$.

Step4: Calculate the area

$A = 2016$ yd².

Step5: Determine measure for walking around

Walking around the field means covering the boundary, so we use perimeter.

Step6: Determine measure for turf - covering

Covering the field with turf means finding the surface - space, so we use area.

Answer:

Perimeter: 200 yd
Area: 2016 yd²
(b) Perimeter
(c) Area
