Answer:
The door should be 1.6cm wide on the drawing.
Step-by-step explanation:
1 meter is 100 centimeters.
Elena's bedroom door is 80 centimeters wide.
To find how wide it should be on the drawing, divide by 50.
= 1.6cm
The door should be 1.6cm wide on the drawing.
Let S, M, L represent the shortest, mid-length, and longest sides, respectively. You are given three bits of information.
.. S +M +L = 14.5 cm
.. L = 2S
.. L = 6.2 cm
You can use an equation something like this to find the middle-length side.
.. (6.2 cm)/2 +M +6.2 cm = 14.5 cm
.. M +9.3 cm = 14.5 cm . . . . . . . . . . . . . constant terms collected
.. M = 5.2 cm . . . . . . . . . . . . . . . . . . . . . subtract 9.3 cm
Now, you know the side lengths are 3.1 cm, 5.2 cm, 6.2 cm.
