How many square feet in an octagon if all sides are 8 feet in length?
To find how many square feet are in an octagon you basicly just have to find the area of the octagon in this problem it would be 8x8 to get the answer how to find the answer is that you must first find out how many sides your shape has then multiply your sides length in this case it happens to be 8 for both of the multiples thus 8x8 equals 64.
How do you do perimeter and area of rectangles?
A rectangle has four sides joined by right angles between adjacent sides. There are two pairs of two equal sides, having lengths A and B. To find the perimeter you add up all the sides, A + A + B + B. This may also be written as 2 x A + 2 X B or 2A +2B or 2 (A+B). To find the area, you multiply A x B. If A = B then you have a square with perimeter 4 x A and area A2
What is the difference between the perimeter and the area of a shape?
The perimeter of a shape is the distance around the outside, for instance, the length of all the sides of a square added together. The area however, is the amount of space within the shape, for example, to find the area of a square, you would simply multiply the length of the side by length of the side.
How would you find the length of one side of a square if the area is sixteen square units?
To find the length of one side of a square when the area is sixteen square units, you would take the square root of the area. In this case, the square root of sixteen is four. Therefore, each side of the square would be four units long.
How do you find the perimeter of a regular pentagon if you know the length of one side?
Multiply the known length by 5, because the sides are all the same length on a regular pentagon and a pentagon has 5 sides.
