Any number between 8-16
If you do 12+5=17 the other side can't be 17 because then the triangle would be flat so it's any number lower than 17.
Also, 12-5= 7. Again, 7 can't be the third side of this traingle because it would make the triangle flat. so any number higher than 7 would work.
Two of them.
You were almost there, 12ft x 5ft = 60 sq ft
73.9583 square feet.
5ft. :/
In general when you think of a cube you think volume. Which would be 12 * 7 * 5 or 420 cubic feet. However, if you mean the area of the outer rectangles, then you need to think about each of the 6 sides. To figure out the area of each side you take the length times the width. There are 2 sides that are 12ft x 7ft - area of 74 ft each, or 148 for both There are 2 sides that are 12ft x 5ft - area of 60 ft each, or 120 for both and there are 2 that are 7ft x 5ft - area of 35 ft each, or 70 for both So the total area would be 338 square feet
If the width is 5ft and the length is 5ft then the area is 25ft. You just need to multiply the length by the width.
Just add together the length of the sides to get the perimeter. If the shape is 5 feet by 5 feet by 8 feet, just add together the sides: 5 + 5 + 8 = 18 feet.
Is 2yd greater length then 5ft

A right angle triangle
the square root of 122+52 (144 + 25 = 169) which is 13.
The triangle only has one height, not two. The height is NOT the length of the other two sides, besides the one it's sitting on. The height is exactly that: the height. It's how high the ceiling has to be if you want to stand that triangle up in a room. In general, the height is LESS than the length of either side that the triangle is not sitting on.
5ft 1
75ft
50ft x 12ft x .5ft = 300 ft3
