Answer: b= 28
A parallelogram has opposite sides parallel and equal in length. Also, opposite angles are equal, making squares, rectangles and rhombuses examples of parallelograms.
If the area of the parallelogram is 7 square units and the height that corresponds to the base is 1/4 unit, then the base is:
A=bh
7 square units= b(1/4)
b=7/(1/4)
b=28
C average speed is used, which is total distance divided by total time.
Explanation:
From the analogy presented, we know that because the speed at which an object travels varies over time, the average speed is used.
The average speed is is the total distance traveled divided by the total time taken.
The average speed appropriately reflects changes in rate of speed with time.
It accounts for moments where a car slows and speeds up.
