An inventor makes a rectangular array of 1024 LEDs. Each row will
have 16 LEDs. How many rows of LEDs does he need?

Sagot :

Answer:

64

Step-by-step explanation:

Since the total area of the rectangle (in this case number of leds) is:

Total LEDs = rows * columns

you can just replace the values:

1024 = 16 * x

And then divide 1024 / 16 to find x

x = 64
