Answer:
Perimeter = 122 cm or 1.22 m
Step-by-step explanation:
The complete question with image is attached.
We know the perimeter is the sum of all the sides.
Since it's already given that one side is 30.5 and we know it is a square, so perimeter would be sum of all the 4 sides [each 30.5 cm].
Perimeter = 30.5 + 30.5 + 30.5 + 30.5 = 122 cm
Also, to get the answer in meters, we need to know that 100 cm = 1 m, hence
We got to divide by 100 to get our answer in meters, so
122/100 = 1.22 meters
Hence
Perimeter = 1.22 m
Answer:
The perimeter of the triangle is 105 cm.
Step-by-step explanation:
The ratio of sides of a triangle is .
The length of middle side is 35 cm.
Let first side of the tringle is , length of third side is
. middle side is of 35 cm.
So, the ratio of length of sides can be written as,
Compare the ratio to get the value of and
.
Now, the sides of the triangle are 25 cm, 35 cm and 45 cm.
Thus, the perimeter of the triangle will be the sum of all sides and can be calculated as,
Therefore, the perimeter of the triangle is 105 cm.
