It's the first one (12, 15, 15, 17, 19, 19, 20, 22, 24)
Answer:
The first one
Step-by-step explanation:
Because you mulitply 4 by 5 to get 20
<u>Define x:</u>
Let the width be x.
width = x
Length = 4x
<u>Given the area, find Length and Width:</u>
The area is 100 cm²
Area = Length x Width
x(4x) = 100
Evaluate the Left Hand Side:
4x² = 100
Divide by 4:
x² = 25
Square root both sides:
x = 5
<u>Find the Width and the Length:</u>
Width = x = 5
Length = 4x = 4(5) = 20
<u>Find Perimeter:</u>
Perimeter = 2( 5 + 20) = 50 m
Answer: Perimeter = 50 m
