Your answer would be A) 108 units3
Answer:
a [2, -4, -6, -2]
Step-by-step explanation:
Guessing and checking isn't the best solution, so I will demonstrate it another way.
Let x be the width. We know that the length is then 2x+5.
So, 2(x+2x+5)=100
3x+5=50
3x=45
So, x=15.
Therefore, the rectangle is 15 centimeters wide.
Guessing and checking could also work. Once you plug in a value, if it is less than 100, than increase you number. The other way works as well.
