A square has perimeter 24 feet. Give its area.

**Possible Answers:**

144 square feet

576 square feet

18 square feet

36 square feet

**Correct answer:**

36 square feet

The perimeter of a figure is the sum of the lengths of its sides. A square comprises four sides of equal length, so, if the perimeter of the square is 24 feet, then each side has length

feet.

The area of the square is equal to the length of a side multiplied by itself, so the area of this square is

square feet.

### Example Question #1 : Area Of Squares And Rectangles

Jennifer wants to wallpaper her room which is made up for four rectangular walls each measuring at feet by feet. If each roll of wallpaper covers square feet of space, how many rolls of wallpaper will Jennifer need?

**Correct answer:**

Start by finding out the total square footage of wallpaper needed.

Find the area of one wall. Recall that in order to find the area of a rectangle, you must multiply the length by the width.

Since we have four identical walls,

Now divide this by the amount of square feet covered by each roll of wallpaper to find how many rolls are needed.
