Answer:
32.625 m
Step-by-step explanation:
You have the proportion ...
18 cm : ___ m = 22.4 cm : 40.6 m
This can be rearranged to ...
___ m/(18 cm) = (40.6 m)/(22.4 cm)
Multiplying by 18 cm gives ...
___ m = (40.6 m)·(18/22.4)
___ m = 32.625 m
Answer: rational number
Step-by-step explanation:
Answer:
I think the answer is linear points
Let x represent the width of the rectangle.
We know 2x=length
Perimeter of a rectangle is 2(length)+2(width)
So we can make an equation for the perimeter of this particular rectangle.
2(2x)+2(x)=60
4x+2x=60
6x=60
x=10.
Since the width is equal to x, we know that the width of this rectangle is 10 m.
And, the length is twice of the width.
10*2=20
Therefore, the length of the rectangle is 20 meters.
