a rectangle and a triangle have the same area. The rectangle has base 5 cm and height 4 cm. what might the base and height of the triangle be? give to different answers.

base 4 and height of 10

base 8 and height 5

Step-by-step explanation:

The area of the rectangle is 20. 4 x 5 = 20

The area of a triangle is  

Multiply two numbers together that equal 40 because you are going to take half of 40 to get 20.

4 x 10 = 40

40/2 = 20

8 x 5 = 40

40/2 = 20

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
