24 feet = 8 yards
18 feet = 6 yards
9 feet = 3 yards

Hey, you gotta know you’re on the right track when all the numbers divide out evenly! Too bad real life don’t work dat way. ‘k. So’s, now it’s important to picture what the question’s about, specially with this kinda dimension question. You got a room, 8 yards by 6 yards, and 3 yards tall. What’s the area of the 4 walls? That’s the real question… a wallpaper or carpet or tile (or anything that goes on a flat surface) question is an area question.

So… each wall got the same height, the height of the room…3 yards (9 feet):

wall 1: 3 yards x ?
wall 2: 3 yards x ?
wall 3: 3 yards x ?
wall 4: 3 yards x ?

So, what’s the width of the walls? well, 2 walls is 8 yards long (the two walls opposite of each other on the sides of the room that’re 24 feet) and 2 walls is 6 yards long (the two walls opposite of each other on the sides of the room that’re 18 feet).

wall 1: 3 yards x 8 yards
wall 2: 3 yards x 8 yards
wall 3: 3 yards x 6 yards
wall 4: 3 yards x 6 yards

To find the area, multiply:

wall 1: 3 yards x 8 yards = 24 square yards
wall 2: 3 yards x 8 yards = 24 square yards
wall 3: 3 yards x 6 yards = 18 square yards
wall 4: 3 yards x 6 yards = 18 square yards

And to find the total, add:

24 + 24 + 18 + 18 = 48 + 36 = 84 square yards

Answer’s 84!

I’m gonna move this to a blog post later, too, with a picture…cuz sketchin’ it out sure can help.

Can you show me how you work with this one ?

A room is 24 feet long, 18 feet wide, and 9 feet high. How many square yards of wallpaper are needed to paper the four walls of the room?

Thanks ,

I came across another problem and can’t figure out how to approach it . It is as follows :

If x= y-3 and y=z^2, what is x in terms of z?

I think this involves the use of exponents stuff but I can’t make it up to work for me !

Let me know man !
