The floor and ceiling are each 20 square feet.
In order to know the area of the walls, we would also need to know the height of the ceiling.
Well, it could be any 2+ sided shapes. A square (4x5), a rectangle (2x6 then 2x4 perhaps?), or any other shape.
[ONLY WORKS FOR REGULAR PENTAGONS] I don't the exact formula, BUT, from what I learned in Geometry last year, I remember that if you have the radius from the center perpendicular to a side [for height] and if you have the length of the side of the pentagon, you can use a simple 1/2 times base time height to get 1/5th of the area. Then you just take that and multiply it by 5 to get the area of the whole pentagon. I know it looks complicated, but it's pretty simple: I have a REGULAR pentagon that I chop into 5 triangles I have the height = 2 I have the base [or the length of 1 side of the pentagon]= 4 1/2xbasexheight= 1/2x2x4= 4 So now you have the area of 1 triangle and multiply by 5 4x5= 20 your pentagon is 20 units squared. I hope this helped.
4X5 = 20 square feet
Depends on how big the bricks are.
100. here's the math: (4x5)x5 (20)x5 =100
No, it is not. 4x4=16; 5x5=25 20=4x5

4x5=20 cs if you add 5 four times 5+5+5+5 it equals 20.
something like 5x4=4x5.
4X90=360 4X5=20 6X5=30
20

There are 4 weeks to a month. 4X5= 20
