1.5 cm is the length of the model.
In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.
Here, we have,
a model car has a scale of 3 cm : 2 m.
The length of the actual hood of the car is 1 m.
Now,
Set up a proportion:
3cm/2m = x/1m
Cross-multiply:
2x=3
Divide by 2:
x=1.5 cm
Hence, 1.5 cm is the length of the model.

Answer:
(B)44
Step-by-step explanation:
It is given that The diagonals of a parallelogram QRST, TR And QS, Intersect at point U, if RS = 10 , ST=12,And RU=9.5.
Now, Since, RS =10, then RS=QT=10 (Opposite sides of parallelogram are equal).
And, ST=12, then ST=QR=12 (Opposite sides of parallelogram are equal)
Thus, The perimeter of the parallelogram QRST is given as:
Perimeter=Sum of all the sides
Perimeter=QR+RS+ST+TQ
Perimeter=12+10+12+10
Perimeter=44
Therefore, the perimeter of the given parallelogram QRST is 44 units.
Hence, option B is correct.
