Lets set up the relationship of the length to width:
l = 3w
Using this, we can make all the variables the same by substitution:
2l + 2w = perimeter
2l + 2w = 72
2(3w) + 2w = 72
6w + 2w = 72
8w = 72
w = 9
The width is 9, to the length must be 9*3, or 27.
Hope this helped!
First, subtract the height he will grow to to the height he is now.
132 - 90 = 42
Now divide this from 3.5.
42 / 3.5 = 12
So it will take 12 months for him to grow to a height of 132 cm.
X = Y - p + q is the answer
Answer:
3?
Step-by-step explanation:
Here is your answer
Let the widht of rectangle be x metres
Then, its length= x+2 metres
Perimeter= 2 (l+b)
=> 34 = 2 (x+2 + x)
=> 34/2 = 2x+2
=> 17= 2x+2
=> 2x= 17-2
=> x = 15/2 metres
Width= 15/2 metres
Length= 15/2 + 2
= 19/2 metres
