A rectangle has a perimeter of 12 centimeters and a height of 5 centimeters. What is the length of the base?

1 cm

Step-by-step explanation:

We know that the formula for perimeter is 2(l+w) or l+l+w+w

We know that the height is 5 cm so that means w= 5 also that there is 5 cm on both sides of the rectangle. So 5+5=10 so that means that the length of the rectangle is 1 cm if you add the length together you 2 when you add the width you get 10. 10+2=12.

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
