Answer:
54 square units
Step-by-step explanation:
One way to find the area is to divide the figure into 3 parts using a horizontal line at y=3.
The trapezoid below the line has bases 9 and 7, and height 6, so an area of ...
A = (1/2)(b1 +b2)h
A = (1/2)(9 +7)(6) = 48 . . . . square units
The left triangle above the line has a base of 3 and a height of 2, so an area of ...
A = (1/2)bh
A = (1/2)(3)(2) = 3 . . . . square units
The right triangle above the line has a base of 6 and a height of 1, so an area of ...
A = (1/2)(6)(1) = 3 . . . . square units
Then the total area is ...
figure area = trapezoid area + left triangle area + right triangle area
figure area = (48 + 3 + 3) square units = 54 square units
Step-by-step explanation:
Motion and rest are two different states of an object. By state of object I don’t mean its state relating to density, i.e., solid, liquid or gas, but the state relating to its position.
If it is put simply, an object that changes its position is said to be in motion. The opposite is rest.
However, perspective plays a huge role in it. Nuclear atoms are always in motion but when we see an object in the macro world or through our naked eyes, it seems to be at rest. Or if you consider Earth, we are always moving around while spinning, and still we can be at rest at times and in motion at times. So, motion and rest are relative to a closed frame.
Considering the closed frame, an object is said to be at rest if it doesn’t change its position at any given time. And, motion is when an object changes its position with respect to time within the closed frame. The state of motion is then subjected to uniform or non-uniform as per the scale of change in position with respect to time. If the scale is uniform at any given time is same then it is uniform motion, else it is non-uniform.
Physics is a little confusing as you gain knowledge. However, the fundamentals can make you quite adept at understanding them.
