Answer:
length: 23 m; width: 11 m.
Step-by-step explanation:
The perimeter of a rectangle is twice the sum of its length and width, so that sum is 34 m. Then you can write two equations in length and width:
l + w = 34
l - w = 12
Adding these together gives you ...
2l = 46
l = 23 . . . . . . divide by 2
Then the width is
w = 23 -12 = 11
The length and width are 23 m and 11 m, respectively.
Answer: True
Let's make 2.2 into a three digit number to calculate and focus better.
⇒ 2.01 < 2.20
2.20 is 0.19 more than the number/decimal 2.01.
So, the answer is True. 2.2 is greater than 2.01.
