A chalkboard has a perimeter of 18 ft and is 6 ft long. Find the height of the chalkboard.

Sagot :

Answer:

The height of the rectangle is 3.

Explanation:

A rectangle has two sides that each measure 6 so the length of both sides would be 12.

The perimeter is 18 so you would subtract 18-12 to get 6.

Because you are missing the height (and there are two other sides of the rectangle) you would divide 6 by 2 to get 3.

So the height is 3.
