Question

the figure below shows a rectangular field. (a) use the calculator to find the area and perimeter of the field. make sure to include the correct units. area: □ □ perimeter: □ □ (b) lisa 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 rectangle area formula

The area formula for a rectangle is $A = l\times w$, where $l$ is the length and $w$ is the width. Here, $l = 78$ yd and $w = 27$ yd.
$A=78\times27 = 2106$ yd²

Step2: Recall rectangle perimeter formula

The perimeter formula for a rectangle is $P=2(l + w)$. Substitute $l = 78$ yd and $w = 27$ yd.
$P = 2(78+27)=2\times105 = 210$ yd

Step3: Answer part (b)

Walking around the field means finding the perimeter. So the measure is perimeter.

Step4: Answer part (c)

The amount of turf needed is related to the area covered by the field. So the measure is area.

Answer:

(a) Area: 2106 yd², Perimeter: 210 yd
(b) Perimeter
(c) Area
