A polygon is given to us and we are interested in finding out the area of the polygon .
- Here we can see that the polygon is made up of a rectangle and a triangle .
We can separately find out their areas and then add them up to find out the area of the polygon.
So that ,
- We know that the area of rectangle is length × breadth and that of triangle is 1/2 × base × height . So ,
- Here height of triangle can be calculated by subtracting the lengths 18cm and 14cm and its base can be calculated by subtracting CD from BD ( see figure in attachment.)
Answer:
a) The rocket travels 200 meters horizontally.
b) The height of the rocket mid-flight is of 1000 meters.
Step-by-step explanation:
Height of the rocket:
The height of the rocket, in meters, after an horizontal distance of x, is given by:
a) How far does the rocket travel horizontally?
This is x when . So
Then
And
So
The rocket travels 200 meters horizontally.
b How high does the rocket reach mid-flight?
This it the height y when x = 0, so:
The height of the rocket mid-flight is of 1000 meters.
