Question

9.Find the length of a rectangle , whose perimeter is 100 m and breadth is 16 m is

34 m
42 m
68 m
36 m
fast please​

Answer 1

$answer$

perimeter of a rectangle is = 100 m

breadth = 16 m

so to find the length =

perimeter of rectangle is

$2(l + b)$

so 2(x+16)=100

2×17=34

Answer 2

Answer:

Step-by-step explanation:

The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object's speed and direction of motion (e.g. 60 km/h to the north). Velocity is a fundamental concept in kinematics, the branch of classical mechanics that describes the motion of bodies.

Velocity is a physical vector quantity; both magnitude and direction are needed to define it. The scalar absolute value (magnitude) of velocity is called speed, being a coherent derived unit whose quantity is measured in the SI (metric system) as metres per second (m/s) or as the SI base unit of (m⋅s−1). For example, "5 metres per second" is a scalar, whereas "5 metres per second east" is a vector. If there is a change in speed, direction or both, then the object has a changing velocity and is said to be undergoing an acceleration.
