x=width
3x=length
3x+x=24
4x=24
4x/4=24/4
x=6
x=width=6cm
3x=length=18cm
18/2=9 cm
6/2=3cm
Length=9cm
width=3cm
because there are two length sides and 2 width sides
The first one is A, the third is D, the fourth is D, the fifth is 4, the sixth is D, the seventh is D, the tenth is D. Sorry I couldn't do all but some.
The formula of the perimeter of a rectangle is equal to:
Perimeter = 2L + 2W
Forming the equation.
<span>Perimeter = 2L + 2W
</span>17.6 = 2L + 2W
Getting the lengths.
<span>17.6 = 2L + 2W
</span>2L = 17.6 - 2W
L = (17.6 - 2W) / 2
<span>17.6 = 2L + 2W
</span>2W = 17.6 - 2L
<span>W = (17.6 - 2L) / 2</span>
10 : 40
divide each side by 40
0.25 : 1

Answer:
The formal operational stage.
Step-by-step explanation:
According to Piaget, adolescents have entered the final stage of cognitive development. The <u>formal operational</u> stage enables adolescents to think logically about tangible and abstract ideas.
As per Piaget: there are four stages of cognitive development.
- The Sensorimeter Stage.
- The Preoperational Stage.
- The Concrete operational Stage.
- The formal operational stage.
The Sensorimeter Stage: It is a stage of age between 0-2 years, wherein kids start using senses of touch, watching and listening to understand and feel the world around.
The Preoperational Stage: It is a stage of age between 2-7 years, wherein kids develop language and start talking about things.
The concrete operational Stage: It is a stage of age between 7-11 years, wherein kids learn logical concrete rule and start having conversation.
The formal operational stage: It is the stage of age group of 11 and above. At this stage children start thinking logically about tangible and abstract ideas.
