A wall in a museum measures 3 meters high by 6 meters wide. One quarter of the wall is dedicated to displays. What is the area of the wall that is dedicated to displays?

Answer 1

The rectangular wall is 3 meters by 6 meters. So what is the area of the whole wall?

Area of a rectangle is length times width, or L * W.

So 3 *6 = 18 meters squared.

Now, we want to find what area is covered by displays. One quarter of it. What fraction is one quarter?

Great, 1/4. So we want 1/4 of the total area.

1/4 * 18 = ____ meters squared. Don't forget units!

Great job!

Cheers,

Margaret

Answer 2

The area of a rectangle is length times width - A = L x W.

Therefore the area of the rectangular wall A = 6 x 3 = 18 square meters

1/4 of the wall is used for displays which means the area dedicated to displays is

1/4 of 18 or 18 x 1/4 = 4.5 square meters
