Question

la figura a continuación muestra un campo rectangular. 76 yd 23 yd (a) utilizar la calculadora para hallar el perímetro y el área del campo. incluir las unidades correctas. perímetro: área: (b) yolanda caminará alrededor del campo. ¿qué medida se utiliza para saber cuánto tiempo tomará? perímetro área (c) el campo será cubierto de césped artificial. ¿cuáles medidas serán utilizadas para hallar la cantidad de césped necesario? perímetro área

Explanation:

Step1: Recall perimeter formula

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, $l = 76$ yd and $w=23$ yd. So $P = 2(76 + 23)$.

Step2: Calculate perimeter

$P=2\times(76 + 23)=2\times99 = 198$ yd.

Step3: Recall area formula

The formula for the area $A$ of a rectangle is $A=l\times w$. So $A = 76\times23$.

Step4: Calculate area

$A=76\times23 = 1748$ yd².

Step5: Answer part (b)

To find out how long it takes Yolanda to walk around the field, we use the perimeter as it represents the distance around the rectangle.

Step6: Answer part (c)

To find the amount of artificial - grass needed to cover the field, we use the area as it represents the surface space of the rectangle.

Answer:

(a) Perimeter: 198 yd
Area: 1748 yd²
(b) Perimeter
(c) Area
