It is a square with lengths of 10 cm
The perimeter is 40cm
10cm by 10cm (perimeter=40cm), 5cm by 20cm (perimeter=50cm), 50cm by 2cm (perimeter=104cm), 100cm by 1cm (perimeter=202cm). All of these rectangles' areas are 100cm2
The perimeter would be 40cm.
First, you must find the width. Use Pythagoras' Theorem. Then, just add the lengths of the four sides, to get the perimeter.
If a regular octagon has a perimeter of 40cm, then each side is 5 cm.
The volume is 502,654.8cm3
P = 160cm
100cm = 1M40cm = 0.4M = 4/10
Perimeter = 40cm. Area = 100cm2
we all know that the square has 4 equal sides and u said that its perimeter is 40 cm then the length of each of its sides is 40\4=10 and the area of a square is stimess which is side times side then its area is 10 TIMES 10=100CM^2 THAT S IT SO SIMPLE ZEINAB SLEIMAN LEBANON BEIRUT GRADE 8 ALBATOUL HIGH SCHOOL TUESDAY:3-3-09
