Answer:
De 8 cada aula
Step-by-step explanation:
Say the width is W and the length is L
L=3W (and of course W=W)
Now you use the perimeter formula P=2L+2W
80=2(3W) + 2W)
80=6W+2W
80=8W Divide both sides by 8
W=10
Now that you know the width, substitute it back into L=3W to find the length
L=3(10)
L=30
The dimensions are length: 30 cm and width: 10 cm
|2.5| because 2 and 1/2 are also 2.5 written in decimal, and the absolute value is always positive
Set x to 0 to find the y value or set y to 0 to find the x value
