A square with 4-inch sides, an octagon with 2-inch sides, several rectangles...
It is: 8*4 = 32 cm
if there 8 sides on an octagon then 8 times 4 should give you your answer which is ....... 32
32cm (8 sides x 4cm = 32cm)
A perimeter is the sum of the lengths of all of the sides to a shape. Therefore, there is no actual number of sides a perimeter can have. A shape has sides. Its perimeter is just a number. If rectangle, then 4 sides. If pentagon, then 5 sides. If hexagon, then 6 sides. If triangle, then 3 sides. If octagon, then 8 sides.
15" x 4 sides = 60-inch perimeter.
4 in2 Square has four equal sides and you say the side is 1 inch. Hence perimeter is 4 inches
If the sides are of length 4 units then the perimeter is 8*4 = 32 units. Its area is then 77.255 square units.
36 inches (4 sides x 9 = 36)
32 inches (4 sides x 8 = 32)
