the area of a rectangle is 105 and width is 5 what is the length?

To find the length of the rectangle, we can use the formula for the area of a rectangle:

Area = length x width

Given that the area is 105 and the width is 5, we can plug in these values to find the length:

105 = length x 5

Divide both sides by 5:

105 / 5 = length

Length = 21

Therefore, the length of the rectangle is 21.
